Thanks for the suggestion regarding the wind noise, Dennis.
I don't worry too much about water leaks, as the only time the car sees water is when it gets washed. Only comes out on sunny/car show days.
I purchased the "how to adjust windows" book from you, and will follow that, see if I can cut down on the wind noise. I realize that, given the design of the G-bodies, I will never get it 100% quiet, but would like to get it so that my passenger and I can have a conversation on the highway, without having to shout!:biggrin:
