I just ordered parts from speedway. 8" dual diaphragm power brake booster with dual chamber master cylinder (1 1/8"). Two 2 lb. RPV's and an adjustable prop valve. I am going to make a bracket that will mount the m/c booster to the existing framework. I'll have to make a slightly longer push rod to connect the pedal to the m/c and I'll have to modify the trans crossmember, if not remove it altogether.
