Im sourcing for a A/c Compressor service Valve for a 1988 Fj62. Ive tried all the traditional ways, and Toyota says theyre discontinued, no longer making them. I need the part that is inside the box that is the diaphragm. Hopefully i can have some of you FJers lead me to a source, or possible replacement. The part im looking for is the small manifold, service Valve that sits above the actuall compressor. Does anyone know where i can find it?
