The biggest problem ends up being the compressor Electromagnetic CLUTCH with using a A6 compressor in a cycling system with R12, or 134a.
Back in the day the clutches, wiring to it, and front seal were common repairs
at the GM dealership I worked at.
While we didn't sell Buicks, we sure did install their "splash shields" on Pontiacs.
