anybody have a disc brake p-valve they will part with for a 72 Cutlass? I pulled rotors and spindles off a parts car i had, but wasn't smart enough to save the p-valve before it went to the shredder. thanks Chad

You may want to consider a new brass one, available just about everywhere now. The original cast iron combo valves often get rust in the bore, which can cause the differential pressure switch to stick on one side when bleeding the brakes.
