I had to go out on the web to see if we were talking about the same animal. Your car would have been called a Fury III. In general, disk brake fitment started becoming more prevalent from the '68 model year on. That particular style body began with the 65s and lasted through the 68 model year. Sometime after that, Mopar starting putting more rubber in the suspension. I don't know the C-body well enough to know when that nonsense began. My best guess is that the 69-73
This may be of help.
65-73 C-BODIES
Early disc-equipped incarnations of these cars used Budd 4-piston brakes, later models had K-H pin type calipers. The K-H brakes are huge, in fact, they are more closely related to D-truck and B-van brakes than they are to any other Mopar passenger car. C-body disc brakes can't swap to/from any other Mopar passcars, and vice-versa. They are, literally, a class by themselves.
Along with the rest of Chryslers models, C-bodies went to 1- piece unicast rotors in 1973. This necessitated a knuckle redesign. The result is simple: for good, lowbuck brakes, with ready parts availability, you need to find a junked (or parked, if youre quick) 1973 disc-equipped C-cruiser, and take everything (incl. rotors, calipers, knuckles, hoses, adapters, etc.) You wont need the control arms, since they are identical from 1965 thru 73. For cars now equipped with 4-piston brakes, you will, however, need to swap the lower ball joints.
Sorry I can't be more help, mate. Here is the URL for a C-body website, maybe they can be more spot on to your requirements.
