Take Bill's advice Randy, those master cylenders are commonly avalable from all of the vintage vendors that we deal with, including the ones that sponsor the 'Bolt. New one will run you about a hundred bucks no matter where you get it. If you are handy and your core is in decent shape, you can save your self quite a bit by rebuilding it your self. They are simple to rebuild, only a few moving parts to deal with.
Just bought a new 1954 service manual my self for $25, although if you look around the are avalable for under twenty bucks.
