Master cylinder interchangeability

[maddart]

I am looking to upgrade my master cylinder on the 1967 coronet, manual brakes (Drum/Drum). Has anyone done this and will a MC from a 70-75 B-body work?

Looking to get away from the bolt on top.

what degree are you upgrading to larger drums, disc up front, disc all around? just for a heads up if you use disc up front you need a disc style master. drum brakes have springs that pull the pads back. disc brakes dont on disc systems the master cylinder actually sucks the pistons back in. drum brake master on disc car and your brakes wont release

no upgrade-just manual drum/drum brakes.Looking for a bigger resoviour with a clip on lid
