Here are two pics of my new sunshade installed by the Louisville dealer last week. The first one is of the front right corner of the roof, the 2nd is the back right corner. As you can see, there is now a wide, covered track that it fits into. The shade was broken right from delivery on 7/15/08 and took this long to arrive at the dealer. Honestly I can't remember what the old, broken one looked like, but I do believe this is a total redesign. At the very least, it works great and feels strong.
Hope this helps those wondering about the new shades.
