[adricar1]

I am looking for a photo please of the proportioning valve and master cylinder piped up in the engine bay 1971 a/c 1/2 t . I have a new master and booster and proportioning valve but i am not sure how the po set this up correctly?

The large reservoir in the master is piped to the front disc brakes to the front of the prop valve and is 3/16 pipe the rears have a largere diameter pipe? should the disc have the larger pipe?
