Master cylinder ?

Hey guys I'm trying to pick out a master cylinder I have been doing some searching and reading on here and it seems like everyone suggests to use s 15/16 bore non power. I have a 75 with front disk and rear drums for now. But in the future I'm gonna be doing a 8.8 swap with disk brakes so I want to pick a mc that will work with both. I found a Dorman 15/16 at summit but it says for power brakes will it still work ok with my manual disk brakes? The part number is
Dorman Brake Master Cylinders M80266
