looking to put rear dics in my 91 std hb, From what iv'e seen all i need to do is to get the new e-brake cable and the disc assembly, i know upgrading my m/c, and b/b ang getting a different proportioning valve will help but are they necessary? anything will help - thanks

 

The MC & BB are not mandatory, but they do help out a lot dealing with brake fade from my experience.
