Disc Brake Conversion Kit (A-Body)

What I have is pictured: 2 backing plates, 2 rotors, 2 calipers, 2 hoses, 1 pressure valve or regulator, some mounting bolts (pictured), mounting studs and nuts (more than what's picture), and that's about it. I also have a new or re-manufactured master cylinder that I would sell for $40 additional.
