This will be my first time doing a conversion on a 964, or any other P-car, to be honest. What are your thoughts?

PS. I just went through the 964 PET and I found the dryer/desiccator, but I don't know the location of it???

Many A/C specialists shops will do the conversion for under $200. My 91 & 92 LS400's, 92 Aerostar, and 88 Carrera were done that way years ago.
88 Carrera still tended to leak until I added a trinary pressure control switch, providing more rear lid condenser cooling via the cabin heater module wired into the pressure switch, and a 15 minute TDR to provide "after-run" condenser cooldown capability.
