rhino, you said the rotors were out of the parts bin with the 4 1/2" pattern. were they B-body rotors, and were the B-body spindles used as well, or did they use different bearings to fit the A-body spindles ? i know i need to get the book.
The rotors were used in 1966 on the Trans Am Mopars. They are a basically a small bolt pattern rotor with bolt pattern drilled differently and machined for larger diameter center register. The spindles and calipers are the same as small bolt pattern production line stuff.
Bob Tarozzi helped on the "Team Starfish" Trans Am car. So he was well aware of special parts.
Here’s Bob’s pin from the 1966 Trans Am race at Sebring
