Proportioning valve -and disk brake upgrade, please help
MY QUESTION: WILL MY STOCK PROP VALVE WORK? DO I NEED TO SWAP PROP VALVES?
Ok, I have managed to confuse myself (which is an all to common occurence). I'm working on /6 1972 Scamp and currently swapping in the Kelsey Hayes set up from a '68 Barracuda. When I bought the set up the seller included a proportioning valve from "another disk/drum car" (unknown year). The date stamp on the prop valve is 188 5 (which I think means July 7, 1975).
This prop valve looks exactly like what is on my all-drum stock Scamp. Both look like:
The '72 Manual describes this as OEM on drum cars and describes a different prop valve for disk/drum cars.
However, Muscle Car Research (https://www.musclecarresearch.com/1970-76-mopar-combo-valve-rebuild) and In-Line-Tube describe this as Mopar's prop valve for disk/drum cars. In Line Tube has reproduced and sells these as disk/drum prop valves (http://inlinetube.com/Prop Valves/BLK250.htm)
Here is the FSM diagram:
