I bought a mc for my 71 gmc a while back from vautozone. I dont remember them asking if it was manual or power brakes. Pretty sure there is no difference as i recall adding pb booster to trucks in the past by unbolting mc from firewall and bolting booster/ brackets and reinstalling mc, never touched brake lines.
