Here you can see the moon roof, and behind it is a custom fiberglass piece that cleans up the roof rack lines and includes an integrated rear spoiler/deflector that all helps lend a smooth look to that area. Tinted windows are going to come soon.
The body was missing the vertical trim piece behind the passenger windows on both sides (as seen in this picture). The pieces are discontinued from the factory, and I was able to buy the last driver's side one in the country left in dealer inventory, but was unable to get the passenger's side one. But, thanks to the help of a reader who happened to spot these pieces in a salvage yard on a Buick wagon I now have the pieces for both sides, plus a spare driver's side one since I'd already bought it from the GM dealer. I am in the process of painting them black to match the rest of the pieces in the area, then putting them on.
