I guess I missed this part - while they can be rebuilt, I have a problem using a clunk master cylinder from the junk yard. You are spending thousands to build a car, why cut corners here. Master cylinders are too cheap not to buy new - a new
Bendix for an '88 Mustang is $37, the older ('86)version, $43 from Rock Auto Parts while a new '79 Corvette, the usual type used on a rod is $43. Equate your time wandering a salvage yard, plus a kit - dang cheap for a new one. Of course "factory" rebuilts are even cheaper yet. Power boosters, if you even need one for a 2800 pound car, a bit more. I have one in my '31 - I forgot to delete that option, but the brakes seem to work fine with it disconnected. If it craps out - it's gone forever.
