could a 71 charger have manual disc/drum brake setup?
My dad special ordered them on his ‘70 Valiant. Cost $49.No idea on a '71, but the Wife's 3600 mile '67 x 383 4 gear Formula S is a front disc manual brake factory car with the broadcast / build sheet to back it up.
even being a dual reservoir, so I assume it's a dual drum master? doubt it's originalIf that is the original master cyl. then, it left the factory with drum brakes.
you can see the prop below the master in the picLooks like the standard manual drum master used in 71. I would check that it even has a prop valve too.
