There are many out there that would poo poo it, but go with F, M, J body spindles, rotors, calipers . . . they used to be pretty plentiful, and they do work. I would get the stainless steel braided brake lines (Dr. Diff) . . .if you "can" find" a mid 70's B body, then you could get the caliper adapter that would allow you to go with the 11.75" rotor. Although the smaller rotor still has better stopping than front drum brakes. Anyhow, good luck . . .
