Dealer installed A/C unit

Hi, I have what I believe is a dealer installed ac unit that I removed from my recent purchase of a 64 Dart GT. I was wondering if anyone could give me any advice on what I should do with it. Since I do not want to install it back in the car after my work on my resto-mod is done. Does anybody think that it would be something that might sell, I know that it works, it just needs Freon or whatever the new stuff is now?
