I had pulled out the funky ARA dealer installed air conditioning, it sort of worked, but I think it had as much leak sealer in the system as it did refrigerant. I didn't realize that dealer installed air was still a big thing in 1990, but the Jimmy was pretty bare bones with manual windows & locks, only a power rear window.
So I sold this pile of stuff to a guy who just wanted the engine compartment box that adds AC to a non-ac inner heater box.
Since it is the wife's rig, and she really wanted AC (even though the top will be off most of the time when it's hot out.....) I ordered a complete Vintage Air kit for it. It will be way cleaner in the engine compartment, and quite frankly I hate dealing with the vacuum operated doors on the factory stuff...

Interior also got gutted again -
