I have a 2003 5.3 from a yukon and the factory compressor outlets hit my upper control arm bracket. I have looked at the camaro and corvette compressors with rear port locations, would they bolt up to my current brackets and would the belt line up?

I also need to know if the compressors are a fixed displacement. Vintage Air says it needs to be fixed not variable displacement to work properly with their under dash evaporator.
