I have a 68 lemans that was power drum/drum.
I had two parts cars over tha past few years that I have pulled parts from.
A 73 camaro that I got the calipers (rebuilt), master cylinder, and proportioning valve.
A 73 nova that I got the spindles, rotors, and backing plates.
Im also running a wilwood proportioning valve for the rear drums.
I have to issues right now.
1. the rear is leaking coming out of the 73 camaro proportioning valve.
2. I have no brakes.

Im guessing that a lot has to do with the leak. But shouldnt I still have the fronts working? Maybe the master cylinder is bad? Should the master be ok for this app? Are the dowl pins different between the drum/drum master cylinder and the disc/drum master? I need to figure this out this week as Im trying to sell the car.
