Compressor upgrade

Be careful what you call an "upgrade". The RV-2 Chrysler compressor is a tough piece to improve upon, especially if it is rebuilt by someone who knows what they are doing with a quality kit. There are still 60 and 70 year old original compressors in operation today. The Sanden is certainly lighter, but that's about where I'd stop. No way does a Sanden have lasting legs like a Chrysler compressor.
