The Stovebolt Site Forums The Parking Lot Big Bolts 62 P30 master brake cylinder alternative.

Hy Grizzlynaut, welcome, the master cylinder I come up with for a 1/2 ton P series 1960 to 62 is Raybestos part number MC 34403, that is a 1 1/8" bore and uses a two bolt mounting which is offset $42.89 at RockAuto. According to my brake parts catalogue the same master cylinder is used on the C series pickups as well 1960 to 62, hope that helps.
