My restaurant A/C guy turned me on to Hot-Shot as a R-12 alternative & you
don't have to change any adapters.  He put it in his car himself.  You
have to order it from an A/C certified person. I sell restaurants & have
run into equipment issues using R-12 and it seems this is the alternative,
especially when it's colder than R-134a & you don't have to modify
anything. http://www.r-414b.net/

I bucked up 2 years and paid about $50/.lb to have mine recharged with
R-12, but since I saw the post I figured I'd share it rather than go
through the trouble of the modification.  Next time I'm using Hot-Shot.
Think!  You can add '92 S4 with "Hot-Shot inside" on your signature and
all the ricers will want to know what that is all about.

That "adapter", perhaps in group buy quantity, is what this list
desires.
Your help in finding the what and where to source this part  would be
appreciated, Chris.

I didn't elaborate before, but it is below the low pressure switch, and
you can just leave the switch disconnected and short across the
electrical
contacts so the compressor will run while using the port.
