what master cylinder for disk/disk set up?

in my 69 dart iv got larger 11.75" disks for the front and jeep cheroke 11" disks in the rear and im needing a new mater cylinder. my 76 dart parts car has power brakes (booster) i wanted to incorporate into my set up. id like to get a more compact master cylinder from a newer model from napa or rock auto but im not sure which one will work with my set up. could i bolt one right to my booster? or would i have to get a matching master and booster?

on other threads people seem to prefer manual brakes over power but im not sure about how much pedal effort my set up will require? theres a 4 speed going in this car so my hands and feet will be all over the place at any given time. i just dont want to be having to pull on the steering wheel to stop the car if a suprise or emergency comes up.
