x2 I would strongly recommend Dr. Diff. I spent years looking and collecting parts online and in junkyards and refurbishing everything myself to convert to '73 duster front disk brakes with a similar year power brake booster system and caliper mounts off a '77 or '78 monaco? (i think) to have large bolt pattern 11.75' brakes. When it was all said and done, I had spent within $100 of just buying Dr. Diffs full stage 2 conversion kit. If I had to do it all over again I wouldn't even question going to him. For the record, my brakes are amazing but it kind of limits my wheel options because I can no longer run 14' wheels. I knew that going in but I just wanted to throw that out there in case you wanted smaller wheels then to just spring for the stage 1 kit.
He has great service and ships fast
