73 and up A-bodies don't even use them. I let Chrysler design the last system on the car I converted. I just used everything front to rear from a 75 Dart.
Seriously? This cant be right. both the 74 and the 2 75 darts I have owned had proportioning valves, or are you saying they were only junction blocks? I have a hard time believing there was no proportioning valve in 73 and up A bodies...
