quote:an aftermarket compressor used in hot rods
These are almost always cheap China copies, nice chrome but lousy unit.
If you want to roll the dice, go for it. Otherwise, seek out a genuine Sanden style SD508 unit.
They come in both flare and o-ring fitting types. And in R12 and R134a types.
This info is correct for Panteras. I suspect the Goose also used the same York compressor.
To use the rotary, you need a common york to sanden adapter plate. Any good ac shop should be able to supply it, or it is usually found on eBay.
Good luck,
