jweb: the m/c was included in the kit from CPP. its a 79 mustang booster & m/c - disc / drum. the instructions say that the chamber closest to the booster ( larger one) is for the front brakes and the smaller chamber is for the rear brakes. to use drum brakes on the front, add a 10# check valve. with drum brakes, there is no proportioning valve.
if changing the rear wheel cylinders doesn't work, the next step would be to chance to a corvette style disc /disc m/c with 10# check valves in each side.
