MOST of the early R134a warnings WERE incorrect!
Conversion on any 1981 & later car with THAT A/C compressor is as simple as draining the old oil...flushing...adding new PAG 100 weight that is compatable with both R12 & R134a..pulling a vacuum & recharging with 70-75% of the original R12 spec.
Remember that that system should have a new drier with a PRESSURE switch as part of that conversion..
