I was afraid that I'm not getting away with this. Ordered a rebuild kit from Jay Stratton.

Just a small update this time.

In the middle of November the parts came back from plating. I chose this particular plating service (out of country) because in addition to yellow and blue they advertised olive passivation on their website. When it turned out they won’t be able to offer it to me I just decided to stick with them.
Although I had everything labelled and sorted into separate boxes they were able to mess up the order and did all the small parts in yellow (as they should’ve) but all the bigger parts ended up white/blue. The smaller parts look really nice. The quality of coating on larger parts, which I assume they did in rack instead of a barrel, was rather poor and uneven.
Ended up taking most of the white stuff to a local plater for replating. Yesterday morning I found out that Google had conveniently moved their e-mails along with some unpaid bills into my spam folder. So, the parts have been ready for a couple of weeks but I’ll be able to get my hands on them after the holidays.

Got some early Christmas presents from my paint guy.

For those who worried - the paint match looks spot on. Image

Now, it’s time to put on our Christmas sweaters and enjoy the holidays with our loved ones!

Merry Christmas and all the best for the upcoming new year!

Oh boy, it’s been a while. Other priorities took precedence, and this project had to take a back seat for a bit. However, every now and then, some progress has been made.

Round two of plating was a success.

Image


With a pile of shiny parts standing by, things had to start going back onto the car. Sunroof installed.

Image

Image


Calipers got plated, then painted silver using Foliatec Brake Caliper Paint Kit. It had some good reviews, so hope it will last.

Image

Image


Hood catches - no olive green for me!

My colleague was visiting some facilities in Texas in December 2023, so I was able to have a hydro booster kit from Jay delivered to him. To be honest, I don’t recall much about installing the new seals, but I guess it all went smoothly.

Image

Image


One of the connector tabs on the brake reservoir cap decided to split in two. After taking a closer look (and being daunted by the price of a new one) I came up with this. The contacts can be pulled out of the cap, so I used a 6.3 mm pin to make a new one. My multimeter agreed with the fix.

Early-model-year-correct front apron — check.

Image


I assembled most of the door hardware off the car. The gaskets got a good soak in Gummi Pflege. A few parts had to come off again after I discovered that assembly order does, in fact, matter. New clips for roof trim.

Image

Door mouldings looked like crap, so I decided to try sanding them. IIRC, I went from 800 to 2000 grit wet, then applied Gyeon ceramic coating. We’ll see how they hold up.

As the old window guides were turning to dust between my fingers, I spent some time online trying to find a suitable replacement. In the end, I settled on this TSEC2300, 16 mm. Ordered 11 metres, which should be enough for all four doors with a bit to spare (in case I mess up). The original channel was asymmetric and sits slightly differently, but this one seems to seal well. Still need to glue the corners.

I messed up installing the passenger-side rear window. I didn’t loosen the centre divider between the rear window and the small triangular quarter window, so the glass got stuck while I was installing it. In the process, I managed to scratch all three black trim pieces on the front and rear doors, so they needed to be repainted.
The driver’s side went better, although the front door glass didn’t move particularly well and made all sorts of noises going up and down. I blamed the aftermarket window channel. (Recently, it turned out to be a sticky power-window gearbox)
By this point, I was getting pretty fed up with the doors, so I left them in that state for a while.

Installed hood insulation which I had ordered from here.

Image


The cable housing for the hood opener was broken in a couple of places. I got some replacement housing and end caps and made a new one. And, as luck would have it, I scratched the paint next to the cable…

Image

Image


A few photos of the steering column, heater core and dashboard being installed.

The last photo is more recent and shows the windshield installed.
I initially bought a URO Parts gasket. After numerous attempts to install the glass with it, I gave up - the upper corners just wouldn’t go into the gasket. I tried the old OEM gasket I had, and the glass went in without an issue. The URO gasket is definitely a no-go. At least I got plenty of practice installing the windshield.

I’ll try to find a used gasket in better shape, though. This one has some mildew spots.

Turns out there’s more to cover than I anticipated, and this post is becoming longer and longer. Seems like a good place to split it. Part two coming soon.
