Might as well throw my .02 in.

Having done a 134 conversion on my '86 as part of a compressor replacement, I have to say that once you consider the cost of the new dryer, the two sensors, the Schraeder valve, the solvent, and the ester oil, you are better off to replace the evaporator. With the stop-leak stuff, you run a real risk of totally hosing your system, having investing several hundred bucks in the R134 conversion.

It also looks like the R12 situation is improving in terms of supply.

These are great cars but you do need to forgive the HVAC system.
