I used a set of Street Rod Manufacturing (In Colorado) rear disc brake brackets along with the small GM rear disc brake caliper with built in parking brake and late model 87 Lincoln 5 on 4 1/2 rear disc brake rotors along with the disc brake master cylinder for that application. This was one of the really cost effective setups....the calipers are plentiful and easy to come by...same with the rotors and master cylinders....the master cylinder is alum in stock form as well.
