Actually yesterday, I finished the project of adding A/C to my 52 GMC hot rod pickup. The Chevy 350 engine already has the compressor on it in preparation for this A/C conversion. I used an old 60's underdash A/C evaporator unit I had around in my parts stash. I also used an old condenser I had, and my only real expense was getting the custom hoses made up. About $200 for the new hoses. Once I mounted all the parts, made all the hose and electrical connections, pulled a vacuum, and charged it up; I had cool air blowing. Very nice having the cold air blowing and the windows rolled up vs 2-60 A/C (2 windows down and 60 mph). Guess I'll find out if the system holds and no leaks within a few weeks. I used R-134a, even though the evap unit was designed way back in R-12 days. It has a thermal expansion valve and it is close enough calibration to work with R-134a. Did not measure air outlet temps, but it seems pretty close to freezing, so it is working well.
Did lots of other house and garage cleaning since it finally cooled down a bit with the monsoon season rains finally kicking in, about 1 month late. Had another couple that are friends over Sat night for a nice dinner and just hanging out.
