Re: Brake Proportioning Valve
Are you telling me that there isn't one available at NAPA, Checker/Schuck's/Kragen, O'Reiley's, Autozone, CarQuest? I'm a NAPA kinda guy myself now. My dad needed a brake booster and master cylinder for our '76, NAPA had NEW units, not rebuilds, for the price of one of the items from the dealership.
Oh, did you try www.ChevyDuty.com
? I would definately not go pull one out of a junkyard, too many unknowns.
