Does a little window like that really make that much difference in the air flow? I'm not trying to be a smart #$$ or anything, I'm actually serious on all of this. I never experienced the 70s muscle cars, wasn't even born yet, so I don't know much about that stuff. I never really cared for the convertables, and still don't, nor am I a fan of chrome, except on the older cars. It just seems to fit then. On things like my Ram, when I had it, it had to be sport because I couldn't stand the chrome.
