I have the complete AC system from a November 1991 XR4x4 sitting in my garage and taking up space. It was working when removed but that was years ago so I don't know if the compressor or anything else has seized. From memory the a/c radiator is ok.

I meant to skip it at Christmas but the snow put a stop to that!

Let me know if some/all of it is any use and you can have it for the price of postage & packing (if you want to give me a Guinness for it, I won't argue!)
