I have found an A/C tech that will come to my home help me with my
Vanagon A/C.  He helped me get the A/C in my 1991 Dodge Colt Vista wagon
going, but in the process, we used up enough of my Freeze-12 stash to
require a reorder before I attempt a refill of the A/C on my 1984
Vanagon.  I filled it with Freeze-12 before, but did not take care of
some leaks and I have not used system for several years.  I know I
should have new hoses made, etc., but I just want to get through the
summer for the time being.

So I have some questions (I already have a new refrigerant drier ready
to unseal and install).

Best source of Freeze-12?
Should I also order Freeze-12 stop leak and Freeze-12 refrigerant oil?
What O-rings do I need for lines to the compressor and the drier and
what is best source?

If I can source for list vendors, that is my preference.

Already have a set of gauges, side-tap for the cans, and two-stage
vacuum pump.
