Lots of people have converted R-12 to 134 on our cars and older 5k's.
You really do loose 10 -15% efficiency with 134 and you have to flush
all the old oil out of the system cause 134 will react with the r12 oil.
I used a Freon substitutive called enviro-freeze (I think), that works
as good as R12. I think it is $6 a can and I put in 2.5 cans ( try
http://www.lenzdist.com/Prods.html . Temp from vents is around 40F
after a few minutes. I also noticed my compressor sapping less power,
which could be due to me adding new oil or all in my head.
