Hi Doug --

Thanks for the info, I've been looking at Freezone along with some others
like R406.  Are you running Freezone in an early '80s AC system?  The
old cylindrical compressor?  I've read that the different styles of
evaporator temperature management among the various generations of AC
systems have different gas requirements, so I'm trying to find someone
who has converted this particular system.

I'll probably have to cobble up some kind of compressor for pumping the
system down, it has been vented down to plain old air.  Wish me luck
finding an old refrig out on the street... with a good compressor...

I haven't a clue about AC, except for books, and I don't know anyone who
does... except for list folks anyway.  Should be fun, eh...
