280z Body Side Molding – Inserting the rubber molding

Finally found some time to start inserting the 280z body side molding!

Last time I riveted the 280z side molding channels onto the body. Now it’s all about inserting the rubber molding. I ordered the 5/8″ rubber molding from CustomAutoTrim.com, and it came to my door in decent time. The size, perfect. The installation? Prepare to take some time to insert the rubber molding. It took a good 30mins to put on just one rubber molding!

What you’ll need to install:
1) 5/8″ Vinyl / Rubber molding (see previous post about 280z body side molding for sizes)
2) Razor
3) Something thin / plastic like a spatula or a guitar pick
4) Tape measure

First, making sure it’s sized correctly! Last time, I ordered in the incorrect one… This one from CustomAutoTrim – perfect.

“Measure twice, cut once” – no no, measure three times. Whenever my mom was showing us how to cook, she’d always say, ‘you can always add, but you can’t take away’. The methodology is still true here, but reversed – you can always take away, but you can’t add. So measure w/ a little excess, you can always trim the molding later. And since I ordered 16ft of molding, I should have some excess…but only for trimming, not enough to complete another channel if i completely screw up.

The vinyl / rubber molding is a tight fit, and getting in that channel can take some time. Here i’m using a guitar pick to help feed the vinyl / rubber molding into the 280z body side molding channel.

Another technique i found to work really well in getting the molding on was to bend the molding like the picture below. This actually allowed me to use the molding itself to help press fit it into the channel.

At the end, i was only left w/ a 1/4″ excess.  A razor helped create a clean edge to butt up against the molding darts ends. Don’t mind the dirty car… after giving a nice wash and wax last sunday, i parked it in lot that ended up getting “cleaned”… meaning leaf blowers. ugh.

Body Side Molding – Rubber Molding

My last post was about putting on the aluminum side molding channels with rivets, so now it’s time to pop in the rubber molding. However… it looks like the molding I purchased is NOT the right one.

Unfortunately, I ordered the incorrect rubber molding from BlackDragonAuto.com. I must have missed that the ‘Body Side Molding’ section was for a 280zx (1979-83), and just looked at the description for part# 97-650 “Adhesive Molding-Black, 16ft roll, cut to fit 280”. Oh well, we’ll try to get that returned if possible.

Adhesive molding from BlackDragonAuto catalog

So I did a little research this morning, and found the CORRECT rubber molding is actually hard to find (neither MSA nor BlackDragonAuto sell it). The proper rubber molding for the 280z can be found at CustomAutoTrim.com. 

[Update, 9/12/24: CustomAutoTrim no longer sells this type of rubber moulding (hence the broken link), but have updated their stock to a slightly different shaped (round) albeit more flexible vinyl insert] updated link

 

Rubber molding for the 280z from CustomAutoTrim.com

This is the correct version because it locks into the side molding “stick” or channel, rather than be affixed by adhesive. CustomAutoTrim also sells the ends of the side molding channels, however the “bullet” and “chisel” ends used on the 280z seem to be discontinued at the time of this post.

If you’re looking for side molding for your 280z you’ll need (at least) the following lengths:

front fender: 23″ per side
door: 32 3/8″ per side
rear fender: 37 1/2″ per side

Total:  185.75″ = 15.48 ft = 16ft (since they sell by the foot) @ $2.25/ft = $36

(Lengths serve as a guide only. Measure your Z for rubber moulding lengths)

[update, 9/12/24: prices haven’t changed that much! Price above was back in 2012. As of this writing it’s available in 7.5ft sections for $24 ($3.20/ft). Not bad!]

Side Molding / Door bumpers

Since re-assembling the 280z prior to the wedding, there’s still remains a few items to be added to the car – yesterday morning, I tackled the side molding (or if you’d like to call them, door bumpers).

These come in 6 trim pieces, each piece having 4 parts: two ends (one pointed, one squared), the side molding rail, and the rubber molding itself. They’re held on to the 280z’s body panels by simple rivets; unfortunately, putting them on initially wasn’t as simple as I had thought!

The information out there on rivet specs for attaching the side molding is scarce. But hopefully with this post, it’ll be a lot easier for someone else to tackle the easy-once-you-have-the-right-info task. Let’s take a look:

Here’s what I used:
Arrow RL100 rivet gun – pick up at Home Depot or Amazon
1/8″ – 1/2″ (3mm-12mm) rivets – you can get an assortment of rivets on Amazon cheap, or you can make life easier and just purchase the rivet tool and rivets in one kit!
A little nut or spark-plug screw head – this will be used to help distance the rivet tool from the rivet head
Painter’s tape – if you don’t have a spare hand to help you, Amazon
#0 and #0000 Steel wool – to clean up the aluminum molding, Amazon

Since the side molding is all metal (save the rubber part), the chromed steel ends and aluminum rail can easily cleaned up with #0 and #0000 steel wool. The ends can be pulled off for further cleaning (there can be lots of dirt underneath). Additionally, Mother’s Aluminum and Mag polish can be used to restore them to a clean shine.

Cleaning the side moulding

Steel wool does the job very well!

Cleaning the side moulding

If you don’t have a spare hand, painter’s tape works well holding up the side molding as you put in the rivets. That way it doesn’t swing on you, and you don’t scratch up that Z car’s paint!

Holding the side moulding with tape

Through some trial / error, I figured out that you need to use the right rivets in order to have a tight hold:
Type – Use the aluminum ones. Since the steel ones are NOT stainless, nor galvanized, they’ll eventually rust on you. Use the aluminum ones.
Ends –  Diameter: 1/8″ (3mm), Grip: 1/4″ (6mm) or 1/2″ (12mm)
Middles – Diamter 1/8″ (3mm),  Grip: 1/8″ (3mm) or 1/4″ (6mm)

Note that for the Ends because they’re thicker, you have to use either the 1/4″ (6mm) or the 1/2″ (12mm). Because the middle portions are thinner, you can use 1/8″ (3mm) or 1/4″ (6mm).

Because the rivet tool head is too large to fit into the channel of the Z’s side molding rail, you need to use a spacer (something to extend the rivet tool head without losing the grip on the rivet stem). I used the head off a spark plug, and it worked great. You can probably also use a small nut. Find something that has a hole large enough to fit the stem, but not too large that the rivet head pulls through. Be careful not to use a spacer too tall, otherwise the tool won’t be able to grab the rivet stem. This trick will allow you to get that rivet head flush against the side molding channel, and set it snug ‘n tight!

Tomorrow, i’ll cut the side molding rubber to length and pop them in.

PART III – WE MADE IT! – DailyDatsun’s Wedding 280z Complete

WE MADE IT – we did it! What started as a daily driver project, transformed into a serious restoration and finished as our wedding chariot. My fiancee and i tied the knot on Sunday, May 27th with a wedding nothing short of amazing. And getting this car completed on time was definitely a part of that weekend. 4 days and 10 people later, the 280z barreled it’s way over to our hotel and drove us to our wedding.

DailyDatsun 280z - Just Married

Truly starting the week before, I had already ordered the parts i had needed for the final assembly – window seals, weatherstripping, carpet, seat covers, and a front windshield (more on that later). I needed to those parts ordered quick to be ready as soon as the car came back. Once the car rolled out of the painters garage it was already Tuesday evening – literally only 4 days and 5 nights remaining. That night i got straight to it, sorting out the pieces getting it ready for a full attack the next day.  We quickly got into full swing with my brother Kris and a groomsman Erik helping hammer it’s way back to road-worthiness.

DailyDatsun 280z - instagram

We were able to complete the rear tail lights, some trim repaint, side marker lights, headlights, hood louvers, hood rubbers, floorboard prepping, and the front feet area of the carpet.

Thursday rolls around for another big day. During the afternoon I had the neighbors install the front and rear windows – truly a blessing to have a family who owns an auto glass repair company live next door to you! Late afternoon, brother brought over another groomsman Jerry and his girl Kennie (who had just both come over from Hong Kong) to lend a hand, helping clean windows and tackle the carpet. Carpet continued to dominate our time because of the measuring / cutting required for all the interior fittings: both sides of the seat belts, shifter, e-brake, and seat rail holes among other things. Carpet needs to go in first because it instantly transforms the visual impact of the car. Additionally, once that’s in, seats, center console, door trim, all that can go back in.

Later that evening, I had three more sets of hands arrive: my future sister-in-law Dana, my sister Kathryn and her boyfriend Jake! It was great, we all had our hands on this thing! Jake and Jerry tackled doors, Kennie and Dana helped clean parts, Kathryn helped me assemble the last seat, while Kris had the dreadful task of installing the rear driver-side interior quarter panel trim. Imagine having so many people who, for the majority, have never worked on cars (let alone re-assemble one) all help out at the same time – yes, it was a circus. Yes, you’ve gotta make sure all the correct bolts were used. But truly it was such a fun experience. I love working on projects with friends, more so with my brother and sister!

To top off the night, even LATER that evening, my parents flew into town, and they too dropped by to check out how things were going. I wish i got it on video / photo, but both my mom and dad would later return the next day to help out to complete the re-assemble.

Friday, My dad and i put in the seats, dash and door trims; while my mom cleaned parts, and even tackled the biggest task: clean / organized the storm of parts and trash that my garage was left in the previous night. Yes, I definitely should have gotten photos of my mom and dad helping out but we were just so focused on getting this done. Wipers went on, the last three pieces of chrome front windshield trim were found and installed. I got to say the whole project has been amazing, but there’s nothing like working on a car with your dad. More over, he’ll be driving it while we’re away on our honeymoon. It’ll be 40 years since he last drove a Z, and I can’t wait to hear what he’s got to say!

I had a two hour window to install the final touches late Saturday afternoon – front grill, front parking lights and their trim, horn, side-view mirrors, and of course, the c-pillar ‘Z’ markers. I took it off the battery tender attached the night before, and started him up. Perfect – solid and strong. Looks – amazing and fast. I’m proud and thankful that my friends and family helped get car back on the road, and ready in time for the wedding.

Sunday night we drove it back from the reception only to be stopped by a police officer 1/4 mile from our hotel. Doh. Were parts falling off? Lack of rear bumper? Nope. No tail lights. Brake lights were working but the car was “invisible out there” with no running tail lights. Luckily the officer was more concerned about our safety, and with the ‘Just Married’ sign and us still being in our wedding get-up we were let go with a congrats rather than a ticket. :] Sigh! now this rebuild story is complete!

Pictures of the re-assemble will come soon – for now here are some pics straight from the painter that Tuesday afternoon.

Getting Wedding Ready – Part II

So it’s been over at Pacific Auto Body & Paint getting the full treatment. Rick has been a great fellow to work with, and keeping both the car’s looks and my pocket change budget in mind. For the time it’s been over there, the 280z has gone through some great personal treatment. Let’s take a look…

Pacific Auto Body & Paint - shop front

After driving it down the shop, he went right away at it with a sanding wheel! WWRRrrrll!

Next, the guide coat. The guide coat is a light spray of color done all over. This helps him make sure no spots are missed! From here, it gets “blocked”. Blocking is a sanding technique of which i don’t know much about, but i know it’s important to get those surfaces even, smooth and consistent.

And then the sealer. Even with just the sealer, you can see the lines really popping w/ all the reflections from the overhead lights. And this is all BEFORE primer!

If you’ll notice in the next picture, we decided to take of the cowl (just above the engine bay) and decided to do it right. He’s gonna black out the inside, and paint in/out of the cowl.

HAPPY 35th BIRTHDAY!

 

YES! In April of 1977, this 280z rolled off the manufacturing line and on to the docks, headed for the Bay Area. Though his 35th birthday would’ve been more appropriate to celebrate last month, I wanted to post it along with his birthday gift – a new paint job.

We’ve decided to take the 280z over to Rick at Pacific Auto and Paint, located on Santa Clara St in downtown San Jose. In the initial scoping for paint, Rick was very enthusiastic and very friendly about getting the car in and handling the job (more importantly, complete the work before the wedding!).

So a short post before a separate painting post, but here’s a few pics to wet the appetite – bon appetit!

Can you figure out what’s missing from this picture?

door locks were actually quite easy

I’ve used quite a few “easy-out” screw removers, but Grabit is awesome. Many of the front valance screws were rusted tight, and the heads got striped while taking them out with a drill / screwdriver. Grabit is a bit with a drill bit on one end and the extractor on the other. A set of 3 sized bits, it was worth every $.

And it made quick work on getting the front valance off.

Datsun 280z: Gutted

Yesterday I started to tear down the 280z.
In about 2.5 hrs, I had the car just about 80% done before it can go to the painter.

Carpet: out.
Seats: gone.
Passenger door: stripped.
Center console: removed.
Passenger side door trim / seal: off.

Just need to remove the driver side door / trim, all the lights, and most importantly the windows…
And I need to make more room in the garage to store all this.

We’ll let the pics do the talking.

Fender Telecaster - Butterscotch Blonde

Well, it’s no secret, the car’s going to (needs to, really) be painted!

Luckily, there’s a great independent paint shop called Pacific Body and Paint that’s local. I got a chance to talk with the owner Ric, and had a lot of great things to say about the 280z – i could tell he was getting genuinely excited to work on the project! He took me onto his garage floor to show me some of his work; talked a bit about his methods and what my expectations were as we circled a early 70’s camaro freshly painted blue w/ white stripes.

I’m looking at painting the car in a 920 Gold Poly, an original 240z color. Interesting thing about this color, are the countless remarks on forums say the original Gold Poly (920) paint you see today is different than when it originally came out (perhaps due to age) – that it used to look more yellow-brownish.
Regardless, this car is going to be painted in a yellowish-orange; very similar to the Butterscotch Blonde you see on classic Fender Telecasters – so whatever that ends up being… 411 Sunburst Yellow?

Just to make sure i’ll like what i’m doing, I’ve photoshop’d a pic of my car not only with paint, but also included the MSA Type 1 non-ducted Air Dam, as well as the ZG flares – both of which are on their way. :] Originally my thought was to have the front air dam painted (which is why the car hasn’t been painted yet…waiting on the part to come in), but I’ve decided to leave the front air dam black to match the flares, and I’ll even keep the lower rocker panel / bottom length of the car black. Seriously, now we’re

talkin’!

Gas Flap Repair

There’s a rubber flap that’s attached to the car just under the gas opening used to protect the car from accidental spillage.

35 yrs and one cold morning later, that rubber flap just broke off.

Picked up a new one from MSA for only $7.95 – Kris and I went to work. You can see the flap retainer is corroded and area under the non-existent flap is a touch rusted and broken.

Sanded the area, picked out the chunks, and bondo’d the gap

Meanwhile the retainer is prepped and primed. The battleship gray primer makes me think the car would look good in this…

While the spray can is out, Kris carefully sealed up the gas opening and we primed the gas tank area. There’s a few pits in the bondo, but i’m not too concerned as it’s going to be covered by the flap.

Gas area gets primed

The gas flap retainer gets painted a few coats of primer, then a few coats of the truck bed liner i used on the door scuff plates.

Finally, the gas flap is installed on the 280z. It won’t matter now, but when I get the car painted, it’ll thank me for it. Like a bib for an old car…

No Bumper – Let the MPG Experiment Begin!

Obviously the Datsun 280z was never purchased as a gas saving, fuel sipping, economy car. Prius’ step aside in horror and repulse as the 280z zooms past their 60mph earth loving vehicles. :] But on the flip-side, with the rise in fuel costs (currently $4.40 for 87 grade gas in the San Jose area), I need to take action.

I found something interesting this morning: my average fuel economy, 18.5 MPG, is actually better than the average passenger car in it’s time!

Fuel Economy History Chart - Daily Datsun

Since my first tank, I’ve consistently maintained 18.5MPG on the 280z (my worst and best being 18MPG and 20MPG respectively).

Now fast forward 35 years, and it’s not quite the same. Though the fuel economy from the late 80’s to the mid-2000’s was stagnant, cars in the past 5 years have had a huge increase in fuel economy (the 2012 Hyundai Elantra pushes 40MPG highway). Though the 280z may never see those types of numbers w/ it’s L-series engine, the alternative to drive train replacement is to reduce weight. This weekend, Kris and i popped off the front bumper, est. a weight savings of ~25-30lbs.
