Hello, did they even have them? I just checked my parts manual and shows non listed, the cab i am using is from an 89 an it didnt have one either, nor did the F model I scrapped.

You can try a 7MT232 guage. It's 3-50 psi, for an RD6 chassis, I'm not sure of the finish on the guage bezel but I would assume it is flat black.

Thank You very much, I know that the guage was an option, we have a truck with one, but no sticker on guage or listing on line sheet. I will give this a shot!!
