A lot of people use the "CORVETTE" manual M/C -- the '65 Corvette was available with OPTIONAL 4 wheel disc brakes -- so they have a front disc - rear drum master available.... and from '66 forward they were 4 wheel disc brakes. This master is very common from many sources.

Wilwood - and their website - has a ton of very good information about pedal ratio - how to calculate size - pressures etc.

When hooking up brake lines - it's helpful - as in CRITICAL - to know which reservoir actuates FIRST - because not all are set up for the front reservoir to go to the front brakes and the rear to the rear brakes. So you'll want to make certain you know what you have. Most of the time - if you're bench bleeding the master - you can see fluid movement in one reservoir just a nanosecond before the other side. The brakes need to be applied FIRST in Front...
