Conversion to R-123A on My 1991 20V Turbo

[Project Pat]

There is such thing as 123, but did you mean 134?

I hear upgrading to a parallel flow condenser helps a lot.
Use Ester oil if any traces of the R12 mineral oil remain.
Probably a good idea to replace the dryer and expansion valve with updated
components.  A shaft seal on the compressor would be nice too if you have
the tools and patience.
Maybe a pusher fan on the condenser if you sit in traffic with the AC
running.
Always replace the service port Schrader valves.  Get the green ones.

This place has universal parallel condensers and lots of helpful info:

Two mid summer drives across mid-America has convinced me I need to get the
A/C back in shape. Considering a conversion. Any BTDT comments (or "Don't
Go There" warnings) appreciated.
