I want my truck to look as original as possible. When replacing the master cylinder, it seems all I could find was a big ole squared off looking thing that did not look at all like the original. Had a single bolt on cap instead of the two wire bales.
Knowing that the bore of my original was 1", I think, I ordered a master for the correct application with the same size bore. I disassembled both, honed out the original to clean it. Then reassembled the old master with the new innerds and it's been doing fine.

Creative 'end around' solution. Kudos for thinking outside the lines.
