First of all a Happy Father's Day to all! My question deals with rear drum brakes. I'm planning on switching a '66-'70 B-Body 8 3/4 complete unit (housing, axles, everything) into our '64 Polara convertible. Seeing that I'll be starting fresh with all parts I may as well put on the largest factory drum brake setup that Ma MoPar offered. I'm thinking that there may be some C-Body brake assemblies out there, or even Pick-Up brakes, that may fit on to the factory B-Body rear end to gain some brake size. Any suggestions?
