I just put AC back on my car...

You'll need:
condensor/fan w/pressure switch
2 under-hood relays (bolted together)
compressor w/hoses
NEW drier ($20 part)
hard lines for drier

ideally you'll get the condensor/fan/hoses/drier+lines as one piece, add compressor and http://www.aircondition.com/tech/que...ing-Procedures

I have a d-series a/c compressor bracket if you need that. PM me.
