The Stovebolt Site Forums The Shop Area Driveline '64 C10 w/ 4 drum brakes, can I add power assist?

Brian, it is a easy swap. Just to clarify, you wont find a rebuilt or new power drum master anywhere, the only thing that is available is the power disc/drum and that works just fine. You can get the booster and MC almost anywhere, so shop by price. After you upgrade to 4 drum power, you can always decide later one about upgrading to discs down the road.
