You can run the factory AC pump as a Compressor if you want to find the factory AC bracketry. This requires an Compressor, brackets, idler pulley, new serpentine belt. You'll need to fabricate an in-line oiler for the pump or risk a shortened pump life, and a intake air filter. Plus the assorted hi-pressure cutoff switch etc. I ran that style setup on my YJ until I did the V8 conversion and switched to York. For what it's worth, the Sanden compressors don't use an oil bath, per se, which really is what makes the Yorks so desireable. Plus the York, generally, puts out more air.
