Thanks

I usually get the booster and MC for a 1987 Regal non-turbo, some early year G-Body units are different.

It really depends on what booster you have.

I'm running a GM stepped bore master cylinder on my vacuum break setup. Believe it's a 24mm bore size.
Works fine. I changed over from the 9" dual diaphragm booster to a B Body 12" Dual diaphragm brake booster and did not experience any issues with either brake booster.
I've attached a link to an article that shows what my brake master cylinder looks like.
