I would recommend that you visit a junk yard and find a truck that has brakes similiar to what you are running, that way you are not miss matching components... in my case, I'm using a manual system off a 76 chevy pickup (front disc, rear drums)... I pulled the differential valve off the 76 truck, and bought the master cylinder and rear cylinders new.. the front stuff came with my hiedts IFS kit...which are the 11 inch camaro parts.
