At least a total of four different fans were tried and I went back and double sealed all the joints and re-foamed the diverter doors. Again a comfortable system, but I haven't been in any early GTO that had good air output out the vents.
On my blue '67 GTO that never had AC I went with a Vintage Air Mark IV system. I told the rep that I wanted to oversize the condenser and compressor and his answer was simply "trust me, the standard ones are great". I installed the system six years ago and it is still freezing me out of the car. Unlike the original system that needed to stay on max, I'm reaching down and turning down the fan speed and cranking up the temp within five minutes even on 100°+ days.
Oh, and weight. I weighed the complete Vintage Air system including the cans of Freon and everything weighed 54.78 pounds. The old A6 compressor by itself weighs 33.36 pounds.
I chose the Mark IV under dash unit because my original heater was working fine.

Great information. I like the Mark IV 'suitcase' system because it looks like the factory AC in my old '64 Galaxie---which looks like a lot of factory and 'add-on' AC systems of the '60's and early '70's. It's attractive, 'period correct' and looks like it belongs there, instead of something from decades after the car was built. If I pull the trigger it'll be a Mark IV.
