Hey all, I'm cleaning out my garage. I have an AC Condenser, AC Compressor, and what I think is an orifice tube. Could these things be worth keeping? I think they are parts of an R-12 set up. I don't know if they are serviceable, the AC never worked and when I pulled the engine out 10 years ago this stuff never went back in. I would like to put AC in it, but might be simpler to start with a modern system. Thoughts?
