Hemi Swap standard AC

I'm not sure what compressor is used on the 6.4 What year is the engine? With a lot of swaps, the only thing that needs being done is mounting the compressor (correct compressor for the engine is best), Making new hoses (if the ends don't match the compressor), and connecting the wiring to the compressor (It depends on the compressor). Don't forget to make sure you have engine/condenser fan operation when the compressor is running, even if engine temp does not call for cooling.
