Anyone have issues with these rotors?
I have AC Delco 18A287 rotors and they don't seem to fit my 92 z-28 10 Bolt with PBRs. I can't mount the caliper without hitting the rotor. The rotor itself is about 1/4 inch deeper than my old rotor. So if the rotor is mounted flush there is not enough room to mount the caliper. I purchased these from Rockauto but maybe they are for a different setup or my rear is not from a 92 Z-28 as previous owner stated. Any ideas?
Thanks

So I finally took the other 18A287 out of the box and low and behold it is the right size. So apparently I have an incorrectly boxed rotor. Does anyone know what car it is from?
Side by side:

Correct Rotor:

Wrong Rotor:

Both came in box marked 18A287...Strange!

Ordered another rotor...This time I got the right one. Not sure which rotor I got the first time.
