66 Valiant, I want to put in front disk brakes, where do I start and a source for parts

copy of the factory Kelsey Hayes. You need 10" drum spindles (I have a set if you need them). Have them on my '63 Dart. They stop... should work with 14" wheels but I am using 15"... the rotors have holes for both SBP and LBP.
