I have a 72 Plymouth Duster Slant 6 225 that has Power brakes with disc up front, drums in the rear. I just purchased a 73 duster parts car with the big bolt pattern disc in the front and drums in the rear and my plan is to swap all the 73 brakes over to my 72. I noticed the mastercylinder and the brake boosters are different between the two. Since the car will have 73 brakes on them, should I buy the a new brake booster and mastercylinder for a 73 duster? Or does is there really any difference? Oh, and will it fit ok on my 72?

I would leave the '72's power booster and master cylinder on the '72. It's the easiest way to go.
