As far as I know the only caliper only kit, for 6 lug, is supplied by Buffalo engineering. As for the other parts needed, 71 chevy k10 parts are what are used. This is the first year for disk brakes so the later years in that design will also work. You need the rotors, calipers and lug studs. I do not know what is included in the Buffalo kit, but you will also need a spacer plate and 6 - 3/8 dia. grade 8 flat head screws. I am not sure of the length, but they will be the same length as the thickness of the hub, rotor and the 3/16" spacer plate. I would think that the screws and spacer are supplied by Buffalo.
The only "machine work" this kit will need is to drill the hub rivet holes out to 3/8 dia. and drill and tape the rotors to 3/8-NC to match the 3-rivet holes in the hub and spacer plate.
