A Body Brake Booster question?

Will 72 A Body brake booster and 73 A Body disc brake MC work together? I want to change to Big Bolt pattern disc brakes but would like to keep my power brake booster.

Yes but you can actually keep the current MC. It does have a smaller rearmost reservoir but that is a safety feature for the masses that dont check fluid levels like we do (Ma dont want any loss of life/lawsuits). Just need to stick a drill bit in the brass inverted cone in the rear threaded boss (for the front discs) where the brake line bolts in to check for a RPV & its just a piece of neoprene & a spring & you will feel it if it has one & if so it needs to be removed for a disc app. odds are good that it ain't got one as they went to a metal disc in the wheel cyls to maintain slight psi as opposed to the (neoprene/spring) 1 way valve
