I just put power brakes on a '71 that came from the factory as a standard, no power disc/drum set-up. The 1975 master/ booster will work fine, but you'll have to make some kind of brackets to mount it. I used the original NON-POWER proportioning valve that came in my truck and it works just fine! Basically, in our trucks, there only 2 different valves, disc and non-disc. They don't care where the pressure comes from!

It's an easy swap and a huge improvement in drivability. You'll love it!
