Don't have any idea about this "stangersite" that you wrote.
But you don't seem to get it at all.
There is no such thing as an Adjustable Kelsey Hayes disc brake proportioning valve, for ANY kind of Mopar automobile.
That's just like trying to pass along fake news, that doesn't exist.
FYI
What showed up on GOOGLE typing in stangersite, has things to do about steering rebuilding, and nothing to do about brakes, or brake parts.
