Well, I'm replacing the compressor because it isn't working.
But my question was what the diameter of the flare fittings were, which after getting the system evacuated at my local ac shop, discovered they were #10 and #8.
Since there's no replacement or NOS for jeep service valves, I posted what I found above which appears to be a direct and interchangeable part.
I'll keep you guys posted on it.
