I had a 69 with factory air with a locked up compressor and a beat up 66 Buick with air and swapped out the ancient, working compressor. I converted it to 134A and ran it for many years w/o any trouble. It blew ice cold air until I sold it.
I have a friend who did a magnificent restoration on a 69 Camaro. His only regret was "upgrading" to Vintage Air rather than staying with the original AC. He would have had a spot on RS/SS. It would now be a major undertaking to switch back.
