When I converted my '64 Polara to Disc/Drum brakes I followed the Mopar Action parts list for everything but the master. I called Stainless Steel brake in SC and got a manual brake twin reservoir unit with a proportioning valve attached for reasonable money. You need more line pressure for the disc side to make it work and less for the drum side to prevent lockup.

Very nice setup..

The larger bore has a firm pedal.

Might be too firm for some..
