72 Duster Resurrection
I think i bought a GM style disc/drum proportioning valve for my 67, but only because my 74 parts car had the same GM style valve in it. May have been cobbled in, but i doubt it the way it was plumbed and bracketed in. Chrysler was sourcing Saginaw PS pumps and GM tilt columns by then so i never gave it a second thought. When i get home this weekend i will check in the brakeline box and see which one i bought. The GM one is more common, works, and is waaay cheaper. I will also take a look because i believe i kept the original proportioning valve and mount bracket off the 74 dart on the shelf. I will snap pix for you if i still have it.
Sonnys car is going to be a disc/disc car, so i will likely source the same style GM valve set up for disc/disc, and plumb it in accordingly.
