Step 3 in the instructions is the AC compressor. Before I removed the old compressor, I installed my AC gauges. There wasn't anything in the system. When I removed it, all I found was some damaged o-rings and no sign of oil or freon. (no suprise)

The compressor that comes with the Rocky Hinge kit is smaller, plus it comes with the required adapters for the common hoses. (nice touch) So far I'm happy.
