Vintage Air or Similar Setup

About 15 years ago I added underdash A/C in my '66 Barracuda, bought the underdash unit, Sanden compressor with universal bracket and valve from Hot Rod Air in Texas, (I think they closed or were bought out a couple years after), as no one showed a kit for the early style water pump.
I have a 360 in my car, used early water pump and factory 2-groove pulleys, the mechanic at the speed shop I worked at took measurements for the condensor, and he made the lines himself as he had the crimp tool.
Where I live it gets over 100 a couple months a year, it does ok inside, but with that fishbowl back glass, it's tough, it's not going to freeze you out of the car, but it's better than being outside! At the time, I think I had about $1000 in parts.
