Plenum Valve
I am looking for a plenum valve part GM 3942618. This is the big rubberized plastic valve that is hinged to the plenum and controls the outside air entering your A/C system. It is pictured on page 122 of the '77 AIM. Does anyone know a source for these as I am not able to find it in any of the current catalogs?
