I received this combination brake valve from a customer who was looking for a rebuild kit for his 1997 Ford Mustang GT. It's marked with an F7ZC-2B091-BB engineering number.

According to my parts catalogs the original applications include the following 1970 GM vehicles equipped with front disk and rear drum brakes: all 1970 Chevrolet, all 1970 Buick A-body, and Oldsmobile F85. The original GM part number for this valve is 1233464; it is stamped 2226261. At some point GM replaced the 3905525 valve with this part.
