Brake System-69 Cuda

I swapped the disks from a 73 Swinger onto my 68 Cuda and the only thing in the doner car was proportioning valve. This bolted directly in place of the drum system distribution block. There is no other items in the system (other than the tee on the rear axle). The proportioning valve has two inputs from the master cylinder, two outputs for the front wheels and one for the rear wheels.
