Did anyone ever figure out where to locate a VAG 1637 A/C service port
adapter?  The responses to this old email message say to visit a local parts
store, but none of them around here have anything A/C related that works
with R-12.   I need to check my system pressures, but can't until I locate
one of these silly dealy-bobs.  I'm sticking with R-12 for now.
