Ari & John - Maybe this is why the pre-'86 A/C is not covered by the
Bentley book?  Honest, unless the hi/lo pressure switch is utilized with
some kind of adapter, we have been unable to find a connection for the
high-pressure gauge.  John, the '85 has the overhead unit mounted up
front, the dryer mounted in the fender well on the left front and I have
been unable to get much in the way of information about it.

Just got off the phone with the VW service manager in Chattanooga.
Heard him ask their sole Van/Vanagon mechanic where it was and heard the
response that it should be in the engine compartment, somewhere..  Asked
the service manager if it was possible that it has NO high pressure port
to connect a gauge.  Said yes.

So, I'm already late for the evacuation/filling party with Randy.
(doesn't THAT sound like an old college frat party!!!)   Will trek on
over to his house, full of Faith that 8.5oz of ester oil and 36oz of
R134a is not going to blow his garage up!  Will report in later this
evening, barring any "911" event.

Has ANYONE seen any conversions to kerosene-fueled, ammonia-based A/C
units suitable for placing in a Vanagon???  Grandmother's old kerosene
refrigerator made it 50 years before it gave up the ghost.
