Both my 1980 and my 86 have a/c - both dealer installed with a factory kit. Because they were import trucks, the A/C had to be installed after they arrived in the states to up their American content, either at the dock or by the dealer. There were 2 companies that made the kits for Chrysler - lone star out of texas, and frigette. Geronimo currently has the A/C out due to me wanting to change from the old eaton style a/c compressor to a sanden rotary compressor and I couldn't find the right bracket for my 2.6. I did manage to score a factory kit missing the compressor and hoses on ebay new for $50, and I intend to use them instead of the original parts on him. The new vintage air mini units should work fine for our trucks, the compressor mount will be the tough part; there is also a tensioner pulley you will need, but one from a starquest 2.6 will work fine. You also need to add another pulley off the crank to spin the compressor - again a starquest will be the best bet - I ended up finding the compressor bracket I needed off of one.
