This rotor swap should work on all 67-72 A-body Mopars equipped with factory KH disc brakes. This rotor swap is intended ONLY for those cars that have KH 4 piston calipers with the 4"bc because of their unique spindles. If the car doesn`t already have the disc spindles,etc. it may not be cost effective. If all of the parts are free and in good condition then you might consider it but it would be a lot of work. The 4 piston caliper is a good braking system usually employed on trucks and high performance cars and is worth keeping if you can.
