Who else have problem with whitepunkonnitro?

sounds like you knew from the beginning they were C-body ......some guys will use them on A-bodies but he has no way of knowing what your going to do with your car.

The bearing retainer is another story but if you didn't message him first then this thread is useless

Are those 73+ spindles you tried putting the brackets on or pre 73? I've never tried it so I don't know but I always thought the brackets bolted right to the 73+ spindles. Am I wrong here guys?

C-bodies do indeed have 11.75" brakes, but they are COMPLETELY DIFFERENT from the 11.75" brakes that came on the later B/R body cars. So, while technically they are both 11.75" brakes, the similarities end right there.

The B/R body 11.75" rotors are interchangeable with 73+ A body spindles and calipers, as well as the F/M/J spindles and calipers. All you need is the 11.75" rotors and a set of 11.75" B/R body caliper brackets.

C-bodies use different spindles, and the C-body caliper brackets will not interchange, the bolt spacing is different. Which is a good thing, because the C-body 11.75 rotors are also thicker, and use different calipers. C-body spindles and brakes are their own thing, they don't interchange with A/B/E/F/M/J/R body spindles or brakes.

And I've bought parts from Tony a few times, never had a problem with him or the parts he sold me.
