Which master cylinder to use?

[csilver]

I purchased a "shell" of a 67 Dart GT that the previous owner put front disc brakes on. Which Master Cylinder will bolt in and offer reasonable street car performance with a 440, manual brakes, disc/drum setup?

A lot of people will recommend the Dr. Diff 15/16" Master and adapter. Are the disc Kelsey Hays 4 pot calipers or 73-up Single piston calipers?

I use a one from a 76 Mopar on my KH manual brake car, iirc it's for power brakes.

Same on my Valiant with manual brakes, single piston disc swap.

Got that aluminum mc with the adapter on 2 other cars, both manual brakes, 1 disc, 1 not.

No complaints on either mc, just what was available at the time.
