As if I didn't feel inadequate enough to build a road racing Camaro before, now I really feel inadequate.  Undecided


Thank you very much Jon. Grin

Sorry, it couldn't be helped.  Grin

Jon in 1970 was most of the camaro's running rear disc brakes, and were they over the counter units or was aftermarket units allowed?

Yes, by 1970 most (but not all) of the cars running in the Trans-Am series were running a 4-wheel disc brake set-up. In 1970, the Trans-Am series started allowing aftermarket brake calipers and rotors. I know that Girling and Hurst-Airheart were some of the brake calipers that got used at that time. With that being said, the factory JL-8 type of brake components were still being used by some competitors and were popular to other teams besides the factory guys because of the more affordable nature of those items.

Jon- Do you know if the "4 wheel disc brake conversion" calipers had "quick change pads". The brake conversion set I got for my '68 Camaro back in 1970 had 4 piston calipers with pads that had a 90 degree tab the full length of the caliper opening (and pad), and they pulled straight out without unbolting the caliper. Just wondering if there was more than one variant. By the way, the inside mating surface of the rotors and the hubs both needed truing up as they had a huge amount of runout as delivered for some reason.

I need to quickly add that I could be wrong about this. Below is the current rear setup on my old car (front is virtually identical) and it may very well be what I put on it. Frustrating that I don't have detailed build photos from the old days.

Here is what is on the car now and may very well be the original factory heavy duty parts option. What do you think?

Sig, I have seen both variants where some people have run the rear calipers with the single pin in the middle and standard looking brake pads and other setups where the calipers have the bent pads held in with twin cotter pins. If you remember the car with the J56 style bent brake pads it would seem that somebody has changed the rear calipers over the course of the last several decades. That would not be surprising.

Yes, you are correct (of course) after some more research I figured out I had the "J50/J56" type dual pin pads and calipers. Used these type pads that are on eBay right now in fact.

The rear shock is dated 8 68 Koni p/n 80E 1953 front shock dated 8 67 p/n 80a-1914 , these are the standard road shocks. The Penske team probably used the double adjustable shocks.

So yours would have been an upgrade from the standard spiral shocks used on the Z/28?

thanks I see it now. I wish it would have listed an application. I know early shelby mustangs used Koni shocks on road courses, I wonder if these were more oriented towards that

Gene, thanks for posting pictures of your shocks. Definitely some rare items. I don't think I've ever seen one with an original box before. More shock information can be found in this thread...
