Thanks to all who chimed in. You guys are an unlimited source of information. Even though it's not correct, I like the vent window on the driver's side. I have fun kidding with my great grandson, when we go cruising on warm Arizona days, that we can turn on the "air conditioning" by opening everything that has access to outside air . We call it 5-40 air. Drive 40 MPH and open the vent window, door windows, cowl vent and side cowl vent. smile smile
Thanks....
