The Vintage Air works perfect! If I had some weather strips on the car, I would keep very cool. I put it in so my wife would ride in the car. She is spoiled. I had to do some fabrication as I have a '74 454cid in a '66 car. difference was the engine had right side AC and the car originally had left side AC. The only thing I don't like is the cheesey cheap plastic pcs. that came with the install kit. I would have preferred stamped metal to go with the original look.
