Scarebird likes to use GM calipers and some rotors, and some are harder to find than OEM Mopar stuff. Also some stuff requires milling.
Why not do the easy F/M/J swap?
I bought a running. driving 5th Ave for $450, and besides the verifiable working brakes, I got a 9:1 roller cam 318, and a **** pile of other parts that work on cars as far back as my 66. Even things like the fender bolts door panel clips, and fender tag screws are the same.
