Take a look at = Wheels of time- I just found out these guys sell vintage air a/c parts at 10% below others . heres the site -lots of other stuff too!!
Twinpilot001, how much homework have you done on A/C? Does that vintage air kit fit under the dash? I've seen smaller units, some with heater cores in them too. A/C is definitely on my list. Not sure if I want it on the roof or under the dash.
I installed an aftermarket AC unit in my truck. I have the 300 so I have the torque. I don't know if vintage AC has the mounting brackets for a sanden compressor to fir our 240's...I asked them and they said no. I don't think the Vertical York compressor will fit due to the height.
