To get the AC functioning again, you will need at least a drier. I cannot believe that the compressor would be any good, and I would be suspicious about the hoses. You can go to R134 if you do the compressor, hoses, drier, and expansion valve. You can probably find a shop in Staunton to make new hoses for you and thus save big bucks.
1982 was the first year for the 300D turbos, so you may have gotten an '81 titled as an '82, but it is more likely grey market. Does it have a mirror on the passenger side?
Don't pay more than a grand for it.
