I have Classic Auto Air in my 59... but it was a toss up with Old Air, as to which one I would use.

I chose Classic because there was a store near me that could service and install it for me.
I found that both were good products and less expensive than Vintage Air.

P.S. my A/C works great. "I really love it"
