After market A/C for our /6?

Hey all. I have a 71 Swinger with factory a/c, that does not work. So I am looking for options to put a/c back in the car. 1) have the factory compressor rebuilt, 2) pull all the factory stuff out and just go after market, 3) use a mix of factory and after market to get it going again.

What would you do? Thanks.
