I have a standard cab 1991 GMC S-15 that came from the factory without AC. I want to put AC in it and was wondering what do I need to put AC in. I know that I need the compressor, condenser, and lines, but what else do I need?

As you know condenser, compressor, lines receiver dryer and the evaporative core that is inside. So you will probably need to change the heater box out too. If you can find a wreck with a/c that will be more cost effective to be truthful. Thanks
