Pulley System

I am probably older than you and I get by. If it's too hot I drive my daily drivers with air.
I understand that, but I want to be able to go to car shows and cruises without sweating. A good friend of mine has a beautiful '65 Malibu that he completely redone, he's been invited to attend the best of the best, but it's black and has no ac and him and his wife burn up going to these shows. The only 2 thing's that I think that he did wrong was, no ac and he left the brakes manual with a single reservoir master cylinder. Other than that, it's a beautiful car.
