I seem to remember that changing to the newer style of condenser is supposed
to help with the help of a rotary a/c compressor.
I converted a 92 Jetta (rotary compressor) to R134a after installing a new
"stock" condenser and receiver/dryer and am very happy with the results.
I converted an Audi 4000S (piston compressor) to R134a and it is about as
weak as it was with R12. :-(
It also had received a new condenser recently and a new receiver/dryer.

I have to repair my 88 GW's a/c system and convert to R134a. I think it
needs the compressor removed, oil drained out and system flushed. Maybe
next year. :-)
later,
dave

LOL the death kit. Someone tried that on my motorhome before I got it and
black death ensued. The orifice was a big nasty black mess.
