In Florida with 1977 Chevy Van g20. Never had the factory AC installed. Apparently there's no kit made for this model / year. Checked VintageAir, etc. Salvage yards seem pretty thin as well. I wasn't too keen on a rooftop unit but it's getting really hot.
New to the vanning scene, so otherwise having a blast! Any advice about where the best places to look is appreciated.
....thought so too. Been to two shops specializing in classics. I'll keep looking. I found Carid.com. They might have everything ala cart. I'm going to see if I can find a diagram of how the system is supposed to look. At least to know where it all gets installed.
