11” drum wheel cylinder bore size question.

I’m currently building currently a street strip 71 Duster with a 410 stroker small block. I’m in the process of gathering the stuff to swap to bigger brakes all around. 73-^ A Body discs up front and 11x2 1/2” rear drums out back. I’ve got a 15/16 manual master cylinder for it the adjustable prop. valve. One of the last things I need is wheel cylinders and I’m trying to get an idea of what bore size others are running with this set up. Thanks in advance.
