I have a 1988 SEC with a 10P17C NIppendenso compressor.  It is a 5 piston compressor.  I guess you call it a wobble plate.  So my project has a rebuilt compressor, new condenser and expansion valve.  New lines also.  I am flushing the evaporator core as well.  I will be using R134A.  When I look at the Nippendenso information I get a number of data much of it contradictory.  One shows if you use R12 then the compressor needs 2.1 oz and if its R134 then 5.2. So I am a little confused here...
