I did eventually get fluid to the rear wheel cylinder, wow can't believe that was 14 years ago. This time around I found the rear rubber hose is plugged.

David are you talking about the brake pressure differential valve that's under the master cylinder? I did take the rear line off of that and no fluid came out, and then I took the front line off and fluid came out of that one. I'm wondering if it might be a master cylinder issue.I haven't touched the metering valve yet.

I checked the brake pressure differential valve and it didn't need reset but I ended up rebuilding that valve and also rebuilt my proportioning valve under the driver's side frame rail, the only valve I didn't touch was the metering valve
 I took off the master cylinder and bench bled it. With everything reinstalled I still have no fluid at the rear brakes. I took off the line just before the proportioning valve under the car and no fluid. I'm not sure what could be wrong, any tips or advice would be greatly appreciated

I contacted Mike, he only rebuilds brake boosters, doesn't sell parts. I found a cup seal for earlier boosters but for some reason I can't find one for a 69.

Ive been trying to find a new cup seal for my power brake booster for my 1969 Camaro. Does anyone know who sells these?

I'm having brake issues in the 69. I have a super hard brake pedal. I thought it was a power booster problem but this weekend I started to look at the front rubber brake lines. I took off both sides and they are ok, checked the steel lines and they look great, no blockage. I went to bleed the whole system starting at the back and initially I had a small amount of fluid coming through both sides. I went to the front and they bled fine. I thought the porportioning valve on the frame rail was bad so I took off the line before the valve to see if it was plugged and it is fine. Now with that line off I apply the brakes and there is no fluid at all coming from that disconnected line. I haven't checked the other metering valve under the master cylinder. Is there someone that sells rebuild kit for these porportioning valves or is there something else I'm missing?

I'm trying to determine if my rear spoiler is a original spoiler or a reproduction. It has AOS 3949798 for the part number and it has 4 semi circular weep holes. I have read in other threads that original ones have rectangular weep holes.

Thats interesting Badshifter, I was told by 2 former owners that my Z28 had a cross ram setup on it. I have always wondered if it came like that from the factory as I have never found the original owner to verify it. Recently I reached out to Wayne Guinn, he's pretty knowledgeable on cross rams. He had me take a picture of the my firewall that I posted on here and to the left of the hole we are questioning there is a ground strap and to the left of that there is a small impression. Original gm cross rams use a v6 pedal and it goes through where that impression by the ground strap is. He thought the hole that we are wondering about might have been used for a after market cross ram. My hole has a grommet in it.

The article in Camaros.org states that it is a 3/4 in hole that was used for the TI wire harness. My hole is 1/2 in. , looks like your's is to. Badshifter did your car ever have a crossram setup on it?

Does anyone know what this hole with the grommet would be used for. This is a picture of my firewall from my 69 Z28. The area pictured is to the left side of the brake booster, just below the wiper motor.

I have, but I've never shown it. I always park in the lot and walk around. My Z is Hugger Orange with black stripes. Is your 69 Garnet Red , I've seen one that color at the show. Don't really see many Z28,s there.

I have a 69 Z28. I've owned the Z since 1988. The car has the original DZ engine but it doesn't have the original transmission. I've been looking for it for 37 years so I feel your frustration. When I looked at Dave's 68 Z , it was a total restoration, it needed a lot of metal work , didn't have the original drivetrain, had some cool options like a tic tok tach and it had a trans in the trunk but I think it was date coded for a 69 Camaro.

He's in the country, he lives on a farm

I live in Maumee. I really hope you can get that engine, sounds like that car deserves to be reunited with it's original motor.

Where are you located, I'm curious as to how far the car is from the motor.
