It not an option to just skip the A/C pulley with a shorter belt?

I think you have to remove a seal and evacuate the system to replace
that bearing. And you'll need a GM A/C clutch tool, if it's like I'm
thinking.

If nothing else, throw a junkyard compressor ($30?) on it and go.
That's what I paid for the last radial R134 compressor I bought
salvage, off a '96 Sonoma...
