I've come to realize that most disc brake master cylinders have 3 3/16 - 3 1/4 mounting centers for mounting to a booster, while the factory drum brake masters have the 3 3/8" mounting centers. I've made one work by widening the holes with a round file, but I'm not really happy with it and it doesn't seem right to me. I've look at the speedway motors corvette style universal MC:
I like it and mounting distance works, but I'm kind of upset that the aluminum version of this MC is listed with narrower mounting centers, as I would prefer aluminum over cast iron. The Wilwood master is also an option considering the factory oblonged holes, but it's on the pricier side of the things. Does anyone know of a factory 1" or 15/16" disc brake master with the factory 3 3/8" mounting centers? I'm not concerned with maintaining a period correct look, so a modern style with a plastic reservoir wouldn't really be a deal breaker. I'm thinking of going with the speedway universal mc, but if possible I think it would be better to build a system off an mc that is widely available and makes possible replacement in the future easier. Thanks! Connor

I used a Corvette MC on my Pro Rally SX/4. I bolted up to the power booster.
I have widened the mounting holes on a 74 Hornet disc/drum MC to fit a 62 Classic without a power booster. No problem. The Hornet MC sure is cheaper than the Speedway one. Nick
