I purchased front and rear disc kits from Matt's Classic Bowties. Classic Performance Products actually supplies the kits to them, but they are cheaper at Matt's. With disc brake 14x7's, I did a test fit and the rotors/caliper clear, no problem. These kits come with the booster and correct master cylinder for your application that you specify. Also, the rears have a built-in e-brake, so you don't have to worry about rigging something up. I can't comment on how it truly fits since I have not installed them yet.
