If you want efficient you definately don't want the RV2 compressor. Use a smaller rocriporcating compresser and R134A refridgerant.
I have most of an aftermarket unit to hang under the ash tray. This is / was a dealer installed a/c.. The unit looks a lot like the factory vent assembly but it has controls on it and it's own variable speed fan in it. These make a little more noise than the factroy fan. They can vibrate and rattle the dash too eventually. I'm not saying this unit is that far gone yet, just stating the differences.
I have the condenser too. You would still need a compressor and you would need custom fabbed hoses.
