I am trying to convert to discs on my car, I have spindles, rotors, calipers,& prop valve off of a 80 monte carlo, I was told these would fit, the only thing I can't remember is what car the power booster & master cylinder came from, I'm thinking 74 to 79 nova. I have read this in a car craft, or hot rod article, & know that this is all a bolt on operation without major mods. Any help is greatly appreciated, thanks
