Here are some pix of the A/C.

I upgraded to a 3 wire 10SI alternator.
The A/C and alternator run on one belt off the crankshaft pulley.
The radiator was fine. I converted from the original 4 blade fan to a 6 blade. I added the two pusher fans mentioned above, but that was more to circulate more air through the condenser than it was to cool the engine.
I also added an idle stop solenoid to bump the idle when the A/C is turned on.
