Used the ssbc disc brake kit on my Barracuda. It was a very easy bolt on installation. The kit is expensive, but it has pretty much everything you need. That includes a dual reservoir master cylinder and proportioning valve. The rotors are drilled for both the 4" and 4 1/2" bolt patterns and both the 7/16" and 1/2" studs are included. If you start out with the small bolt pattern, you can upgrade to the larger one later.
