I'm going to put out a general question, the TSB in question, 95-01 or 95-03
or something like that lists the same old O-ring part numbers.  ARE the
(black) O-rings being supplied to these numbers (same as they ever were in
apopearance at least) R-134 compatible or not.  When I bought a
reciever/drier from FLAPS I got green O-rings as I expected, then I went to
buy the rest from VW (ludicrous mark ups) and have been supplied black
O-rings.  Now frankly I know O-rings a little bit, have designed oil/gas
sealing systems up to 60ksi pressure, so I realize color doesn't imply
formulation and doesn't scare me but I have no way of knowing if the ones
I've been supplied are a compatible formulation or not.  Anyone know, the
parts lady (who has been there 15 years and is the only person at the
dealership I remotely trust) said when she heard I was converting, don't you
need green ones?   Although she said the new cars used the green ones with
R134, she had no source of a cross reference to supply them for older
vehicles (my '85 Quantum and the '87 van in question.)  Anyone who has been
supplied a green O-ring for a van or anyone who has used a black one happily
for a year or so without major leakage, please help???
