I have to replace the compressor on my 86 740. After 300,000 miles, my AC
man tells me it's giving up the ghost. He says replace the
compressor/clutch and receiver/dryer and he'll recharge with R12. But at
$60+ per pound I'm wondering if 134 is the way to go. Mr. AC says since
there are no system leaks, and it cools fine, keep the same refrigerant.
Comments, please.

Keep in mind that you have a bunch of old A/C parts, some of which will
probably fail in the next little while. So it's probably best to do the
conversion now, so repairs to follow won't be so expensive.
 
Screw R12, I did the conversion on my 740 in an afternoon and filled it up
with R134a, it works great, is environmentally friendly, and costs only
about $20 to charge.
