The roof rack keys should be available at any GM dealer and the top weatherstrip piece is also available from GM. I'd get the top weatherstrip from GM because aftermarket ones have a history of buzzing and making noise. I wouldn't be suprised if your side windshield peices need taping down with the elements getting to them from the top. Those pieces can get very noisy at highway speeds if not fastened properly. The folding mirror mechanism is expensive to replace and has a history of going out. If you can live with it, I recommend putting that at the bottom of your to do list. Congrats on your purchase, you'll love it!
