How about the expansion valve?  I just did the R-134a on mine and chose to
replace that too.  It was a major PITA to remove the evaporator, but at
least I got the opportunity to vacuum out all of the dust and rotten foam
that was clogging up the fins.

Also,  I am not convinced that I got all of the R-12 oil out of my new
compressor -- probably an ounce or so left.  I hope this doesn't clog up
anything in the future.  Also, I couldn't find blue O-rings to fit the
compressor ports on my Sanden 711 compressor.  Again, I hope that this
won't mean I have to charge up the R-134a every year!  Anybody know how
much potential loss there is from 2 O-rings?  I changed the rest of them.

Thanks,
Michael Townsend
