A friend has a '72 Nova with front disc brakes. Will the complete setup (rotors, power booster, etc) fit my 1972 Chevelle without the need to purchase any other parts?
Which other cars have front disc brakes which will drop right in to my Chevelle? Thanks for your help

Grab them. Will work fine. You will need to use the steering arm (bolts to back of spindle) from your chevelle. Don't miss the proportioning valve-located on frame rail below master cylinder on the chevelle, probably similar location on the Nova. Also you will need to replace the flexible hose from the frame to the caliper.

Donor cars - 68-72 A Bodies, chevelle, le mans, skylark, cutlass, monte carlo, grand prix. 68-74 F-Bodies. Camaro, Firebird,
68-74 X-bodies Omega & Apollo, Nova Ventura (?).

I believe the nova/camaro steer from the back. But I think if you change the steering arm to face the front they will work.

Sprinter is right. Just reverse the steering arms to the other side of the car. I had the same setup but never installed it. Went to tall spindles on my 64.
