The guy I talked to had a VIR system that he rebuilt on his '76 El Camino
Classic. He's not sure whether my '76 Sprint has it but it strikes me that he
would be able to know the difference. While I was talking to him, it became
clear that he knew alot about R-134, R-12, and something called "Freeze-12"
which I gather is an aftermarket refrigerant meant to put in old systems. I
know absolutely nothing about A/C, but this guy seems to, so I think it's time
to hire him sometime before he retires. When I test-drove his El Camino, the
A/C was not working. According to him, it is working much better now. I
enjoyed talking to the guy, so we'll see how this works out.

The bumper jack went away around 80. Kellys 78(IIRC)
had a bumperjack. I still have the original click sissor jack in my elky. They
work surprisingly well though slow.
As for the VIR.. It was a hard to diagnose system and
failed often but.... When working right it's a really cold system. It's similar
in operation to some of the chrysler cars that used expansion blocks with EPR
valves but used different parts to get the same result.
Anything with an EPR will cool better as
it keeps the pressure in the evaporator constant so it controls refrigerant
boil
off and surging through the system. As such it smooths out the operation of the
AC. So at times when you nail the gas or let off the gas it can maintain the
same cold evap temp. I had thoughts of retrofitting an expansion valve and EPR
to mine and making it ice cold but never got past the thought part.

Just a little thought here, but how many of you still have your original bumper
jack? Both my '76 and my '73 did not have the jack present when I bought them.
Fortunately I bought one off ebay a few years ago so it is now stowed in my '76.
