Classic Air vs. Vintage Air

I have Vintage Air in my '64 Valiant convertible, and it will freeze you out in 100+ degree weather.

I also have a Vintage Air in my '73 D100 standard cab, and it barely keeps it comfortable. If running on high, the system develops annoying harmonics.

Tech support was excellent during both installations, but they didn't know Mopars, so I had to be creative.

Part quality has been good, with no failures or warranty returns required, but performance is a mixed bag.
