Ok, planning on using front brake stuff from a 73 duster on a 69 satellite. Satellite is currently manual drum , duster was power disc. Could I use the power booster and master in the satellite without modification or shortcomings (pedal ratio, etc.)? Also, the only thing not saved from the duster was the combination valve. Whats the best source for one? Thanks for any input on what Im sure is an entirely over asked question.
