try Autozone. a/c compressor for an 81ish Volvo is what your looking for. they're the same one's that A.R.T. sells for almost a grand. they're remanufactured and sell for about 150, that's including the core charge and it comes with the clutch as well. u should be able to find plenty of info on the web about mounting them and what extras u will need for it. good luck.
