replacing master cylinder and prop valve after disc brake conversion

[kmaz]

Hoping someone could provide some direction. I have a 69 c10 short bed that I am currently restoring and just completed converting all to disc brakes...also ran new lines as well... the truck was originally a drum/drum power brakes truck. Now I am looking for a inexpensive way for a disc/disc master cylinder and proportional valve?? I was told I could use a 75 corvette disc/disc mc and PV? Is this true? Any help would be greatly appreciated.

Thank you
