Ok...this is great for York compressor folks, but what about us
Nippondenso folks(ie, all type 44's after about 85-86?)

I like the part about more heat transfer...black car, black interior, and
my current A/C just can't keep up.

Every so often, we hear someone ponder or talk about replacing the $$$$
Nippondenso compressor with a rotary scroll or similar.  Did anyone
actually ever come up with a complete solution?

Autofrost just came up on the 200q20v list, so I'm cc'ing it...
