A/C compressor clutch question

[Guess]

Good news. I converted over to R134a and it blows cold air. However, the compressor clutch started squealing like the bearings were no longer lubricated.

Can I just buy one of these and replace it or do I need a whole new assembly?

If so, is it easy to replace the bearings?

If it isn't wobbling and wearing out the snout of the compressor, you can get away with changing out the clutch and windings and 2 snap rings.
