thats an impressive photoshop, and damn beautiful!

i assume project #3 will be some sort of trunk chop so we can see your spare tire?

Thank you! And I was thinking LED valve caps.

Almost done already.

Oh shit. Is this glass or some form of plexiglass?

How'd you get the bend?

Oh...is this a shop?

The chop top shop in the shop made my eyes pop. twas a quality shop. i'll stop.

I cried a little when I saw the broken window. 

Cool Project.

Cher sent me one of his light painting images. I had to share!

Cher edited the rear view of my car on a whim. Other than that, I have yet to start working on this again, but it is getting closer to the top of the list!

LOOOOOOOONG overdue update on this car. 

I got all the parts I need to swap the brake system(I think). I called Wilwood and figured out the exact calipers I got from @DrLeadFoot because I needed to get an idea of what size masters I should run with the pedalbox and the calipers front and rear. Despite everything I read on the internet(5/8ths F&R), I wanted to be certain. It turns out, due to the size and stroke if the rear Calipers, Wilwood suggests a 3/4th master for the rear. The front calipers are an older design (cast with raised Wilwood logo) which I actually prefer but still utilize the same parts as the new design (cast with printed logo) and wilwood said a 5/8ths is perfect for them.  

So here is what I ended up getting;

• Wilwood 4 piston Forged Superlites
• Wilwood 11.75" Ultralite 2 pc rotors
• Wilwood BP-20 pads
• Wilwood 340-11299 pedal assembly
• Wilwood 5/8th master for the front
• Wilwood 3/4th master for the rear 
• Wilwood 3/4th master for the clutch
• Garagistic mounting bracket
• Wilwood bias valve

Size comparison of the rotors 

The old brake setup

The new brake setup

And a test fit with my wheels

Super stoked that these fit with ample room left 

It took me about a good 3 hours to fit everything and trim the heat shields and find hardware that would work for mocking up.

As of now I only have the rotors and calipers installed just to mock them up. They will be coming back off and the new rotors will go on, the hats and calipers will be painted and rebuilt before finally assembly.

The next steps now is to get the pedal box to fit in the car. It says on the garagistic site that I need a non-airbag steering column, which I am going to soon learn the reason behind.

@johnprusinski might have some tips, I remember he had some choice words about that garagistic setup.

He already mentioned to me that it’s a huge PITA.

[Jdesign]

Calipers are all painted and I cleaned up the hardware. I was going to get new pad guides instead of cleaning them but they were $80 and I realized I was just being lazy. 
 

 

I have yet to start digging under the dash, that’s next.

[Jdesign]

I started on the more frustrating part of the brake upgrade. So far I haven’t determined that I can use my airbag column per garagistics instructions. But they also said I need to remove my dash, and I proved that was a lie already. 

Here is all the factory parts out of the car..

This is a shot of the garagistic bracket mocked up before I drill the holes in the firewall. I later noticed before I drilled the holes that I was off by 1 bolt and had to shift the whole thing to the left. I’m glad I noticed before drilling.
 

I also have to modify the throttle lever. Originally the throttle cable exits far to the left of the pedal assembly. I had to cut the cam portion of the lever as it hits the clutch pedal if you don’t. I plan on welding it above the pivot of the pedal itself. That’s what you can see mocked up here. What’s nice about this is that the cable will now exit right behind the manifold and give it a cleaner look. 

The pedals in their final resting place. Unfortunately they will probably come back out a few more times as I route the brake lines and reservoir lines. 
 

here’s a shot of the bracket and bolts that you have to drill into the firewall.

This last picture is just a picture of my carpet. I used drawer liners to protect the carpet from getting dirty as I’m crawling out from under the dash 40 some times fitting everything. I use this stuff all the time to protect surfaces. It doesn’t leave any residue and is around $3 for an entire roll of it. 

[YoungCR]

I don’t see how removing the dash would’ve been helpful except for maybe those 3 bracket bolts? You don’t gain much access with the dash supports still there which you had to work under for most everything. Nice progress!

I agree, It seemed really pointless. I can't imagine someone doing it and gaining much from it. 

I tried to mount the column and it seems to run into the master towards the center of the car. I have a few leads on a early model column, but I am also considering a flaming river shaft to join the rack to the column in hopes to clean all of it up under the dash and in the engine bay.

[Jdesign]

Well I spent most of my saturday trying to sort out my steering column issue. It turns out that none of my current options left me a happy camper. I did get myself an early model non-airbag column but the way it fit was very unfortunate. not only did it put the steering wheel angle back at the bus driver position that I hated, it also pointed the face of the wheel a good 5-10 degrees toward the drivers door. Apparently the hole in the firewall is different on the late model airbag cars.

Here is the two columns side by side

Here you can see how dramatically left the column faces

Here is the bus driver angle 

So my plan from here was that it would be easier to make my airbag column work. Below you can see how close one of the masters is to the splines of the column. I drew a line in red that shows where the shaft needs to go. Notice that my line is a "Z" as it not only has to go to the right, it also has to pivot down. 

This is my solution; use a flaming river double U joint to make the "Z" and then a D shaft through the firewall and a second U joint to mate it to the Z4 rack. the second part im still not sure I have all the puzzle pieces yet. I previously made an adapter a few pages back in this thread to mate the Z4 to my column, but now I am using a D shaft, I will likely have to make a different adapter. I just ordered everything and will have to figure this out when I have everything in my hands. 

If anyone knows the spline count on the shaft of a Z4 rack, please let me know. I looked high and low and found nothing. it measures to 18mm on a caliper, but I had a hell of a time trying to get an accurate spline count. It is NOT the 17mm 54 spline that is commonly used.

[Jdesign]

Welp. Parts came, and I’m an idiot ( which is evident) both joints I ordered were wrong. New ones are on the way now. Basically I read the specs off of R3v and just considered them accurate to my car without checking completely. 
Here’s a picture of what I got, and sent back. 
 

the correct (I think) sizes I ordered as are follows:

3/4” (19mm) -48 spline (z4 rack shaft specs) into a 3/4” D shaft

3/4” D shaft into

Double U (17.5mm)11/16” -36 spline (steering column specs)

In other news, I ordered a replacement for my radio din since I have the Bluetooth amp. I will need to create a surround for it, and texture it to match the dash, but I think it’s a better idea than just a block off plate.

That is awesome!!! I've been hearing more and more of people switching to those bluetooth amps and what a great addition to the interior of the car.

Mocked up a bracket to mount the reservoirs. I drilled the holes in the rain tray, added grommets and ran the lines to the masters. I ran into a small issue that I might be able to solve quickly once I pull everything back out again. The middle reservoir line is right where two layers of sheet metal split, so one side might need to be trimmed from under the dash. I am NOT looking forward to that.

The new joints showed up, and to my surprise, the second time is a charm. Everything fit perfectly! (Minus the fact that my D shaft is about 4" too short, HEH ) 

Under the dash its REALLY REALLY tight to the master. I actually had to shave the mounting bracket for the pedal box and the master itself to clear, but it looks like its going to work!

Here is the engine bay side of the D shaft and the new U joint to replace the one I made previously. It looks much nicer and is a lower profile than what I had. 

I ordered all the lines and fittings for the masters and started to mock all of that up as well. My biggest challenge with that is figuring out where I want to drill more holes for the bulk heads in the firewall. It already kind of looks like swiss cheese, and I figure I will weld all the holes shut once I paint the engine bay, but I rather get it right first than have to revisit it later.
