I have vintage air in my 51. If I had it to do over again, I would go with classic auto air. My vintage cools decent but I don't like several things about it. Install instructions are about as clear as mud, lots of things you have too figure out and do things twice when you figure it out. Controls are not back lit, I had to use a sanden mini compressor with my LS and it moans no matter what I've tried to get it to shut up. My brother builds classic vehicles for a living and classic auto air is his choice as he's used them all.
