Do not know of any other fancy way to tighten the belt. Maybe wrap your choice of pry tool with a rag to try and save your nice paint.

I do not believe a factory a/c setup has a low pressure switch.

To the OP: Avoid over tightening the belt as that just puts undue pressure on bearings. Why leave the tightening of the fittings to a pro, nothing magic about tightening up the line fittings...just don't be a gorilla. If are converting to R134a, did you flush the system to remove all the mineral oil? Are you upgrading the condenser? If you leave the line fittings loose, you risk allowing moisture into the new (assumption) receiver/drier. Not the end of the world, but will require a longer evacuation time to boil out all the moisture and dry the desiccant.
