What master cyl for brake swap? 73 and up AND Ford rear end

Hi guys,

What master cylinder would you recommend I get for a brake project?
64 Cuda
-front discs from 74 Duster
-rear discs from Ford Explorer 8.8 rear end
-going to run manual not boosted

I know I will need a proportioning valve but not sure which Master Cylinder is best.
Thanks in advance!
