I looked at the Camaro rotor and I didn't see an easy way to redrill it for 5" bolt pattern. I wish I had known about the 89-96 Caprice rotor.
I am using a Lincoln rear end that has disc brakes and has a 5X5 bolt pattern. In my case it would be easier to redrill the rear axle and rotors for 5X4.75 to match the Camaro rotors.
