I am speaking of my '79 SD. It's too hot again thsi summer and I've sworn tp myself that I'm going to have A/C this summer. Anyways, my mom's cousin has manifold gauges for r22/r12. They don't fit my fittings.
My fittings have the needle maybe 1/4" down in the fitting body? So when you are looking at the fitting, the needle piece is 1/4" below the surface? I am speaking in idiot terms, I know, so please be gentle. Do these seem like r-134 fittings? The threads are in the inside of the fitting if that helps any.
Thanks
David
