I have been working on detailing the engine and of course discovered a broken a/c compressor mount. I since welded it. My question is whether this type of compressor still used the R12. No one seems to know when I brought it in for service. Compressor is large square unit and is hard to see in the pic. Ports are labeled Suction and Discharge at the top. Dash air does not work. Previous owner had declined to service it and in their paperwork their servicer stated they had no idea what type of refrigerant was in the system.
