4 years and counting.
I've converted my E30 to R134a after moving to TX. Under $100 in parts and
2-3 hour of labor later the car has been cooling to 38F at the center air
vents on a 90F day (at 2K RPM).

What lubrication issues?
You must drain the R12-friendly oil out of the system during conversion and
fill it up with an R134a-friendly juice.
Issue closed.

Why?
You would put a flamable gas into your AC system and risk a $27,500 fine
per day and 5 years in jail for what?!?

Nope, R134a is not ozone depleting chemical.
CFC-12 (aka R12) is.
