Hello all-- I'm back into the Chevy game with a really pretty 1980 1/2 ton Scottsdale with a 250 in her. Has anyone done a stock AC retrofit? What do I need to look for? Thanks in advance for your advice. Joe Near Des Moines, IA
You basically need everything from a donor truck to convert to a/c: Inner ducting/box Outer Box/Evap case A/C controls/wiring harness A/C system (Evap, Dryer, Compressor, etc) Compressor and Condenser Brackets Heater Core The biggest thing is that you need to patch the old heater core/duct holes on your firewall and cut new ones for the A/C and new heater core. I did this a few years ago when I swapped my engine out, so I had pretty easy access to the firewall (no fenders, hood, or engine in the way).
