As long as my car is enjoying it second money dump, er... I mean
restoration, I felt it an appropriate moment to convert from r-12 to r-134.
I have a few questions for those in the know.

1) I have a rotary compressor purchased in '92 with probably less than 20
hrs on it.  Do I need to replace it with one specifically designed for
r-134?  The flush that I purchased recommended not to use it in the
compressor.  If I am able to reuse the compressor, how do I remove the
existing oil?

2) I am rerouting new AC hoses from the condenser to the compressor and
dryer(relocated to the firewall under the voltage regulator etc.).  I am
considering using Russell fittings to pass the lines through the inner
fender well sheetmetal.  Are the flare's angles compatible?  I am also
considering Air-tique AC aluminum bulkhead fittings viewable at
http://www.air-tique.com/hose.html.  Has anyone an opinion on this type of
o-ring coupling?

3) While I am using a new condenser (Thanks insurance company as the truck
cracked the original), I am not able to flush out the evaporator while it is
in the car.  I blew compressed air into it and no oil exited the other
fitting.  Any suggestions or am I probably alright?

4) If I need to change compressors,  anyone want a deal on good as new r-12
rotary compressor?

Thanks
