Replacing stock variable a/c compressor with something else??? Is there a sanden or other style a/c compressor out there that will mount in the same location as the stock LS2 V7 a/c compressor? I'd like to run a/c in my car, but I'm not looking forward to the misc sensors and controls to get the variable style compressor to work.

I remember someone saying the early Gen III trucks used non-variable ones. May be check those out 99-2000?
The refrigerant AC pressure sensor has nothing to do with using a fixed or variable displacement compressor. The AC pressure sensor allows the PCM to do the functions of a trinary switch (cut out compressor at high/low high-side pressure, turn on fans, and kick up idle). I'm using a 99 LS1 Camaro's refrigerant AC pressure sensor with my Sanden compressor and Vintage Air GENIV system.

If you want you can convert your compressor from a variable to a fixed. I posted a thread do a search. I am going to use my compressor with a vintage air setup. Don't believe that a variable compressor will not work. The biggest issue is that the rest of the system should be setup for a R134 and hopefully not a R12 retrofit setup.
