Most parts houses sells a kit for doing the upgrade. I believe you'll need
a new evaporator, the kit has all the o rings you'll need for replacement.
You'll have to evacuate (properly now) the old refrigerant from the system,
but since your compressor locked up you of course need a new compressor.
Which should come R134a compatable. I did this conversion on my blazer and
had no problems. After everything all mounted back--you have to vacuum the
system down with a vacuum pump...let it run a good while to evacuate all
the air in the lines. The r134a has different connections for adding
freon-which comes with the kit as well.. -wayne
