Go with the Vintage. Much more efficient evaporator and condensor. Modern compressor and high efficiency blower. Just like a modern cars a/c,..because it is.
You can trust me .
Thanks Leo. I have recieved a few PM's and they agree that the older system is...just that. Old. Since I am not worried about originality and want to put some real miles on this car, I will go with the vintage air. I wanted to decide before I got into redoing the car. I will weld up the factory a/c holes for a cleaner firewall.
