My '72 in a non-AC cab, but has the Dealer installed Harrison under dash AC unit (like the pics in this thread -
http://67-72chevytrucks.com/vboard/s...light=harrison ), which I'd like to keep. Are you able to get a kit with the compressor, hoses, and all parts that I would need to upgrade it? Would I need to change the evaporator and/or condenser to work better with 134A? If so, my zip is 78645 for the shipping estimate. Thanks!!
