I've checked both my sunroof cars and one is missing the felt like strip that attaches to the front of the opening, there is a series of closely spaced holes around the opening, presumably to fasten the seal. I was able to get the photo from the other car of this seal and it is a white felt-like material with an embedded rubber strip at the top, some of which has slipped down in places. Unable to tell if it is retained by clips or just glued in. There is a rubber seal at the back of the roof panel that seals the back of the opening when the panel lifts into the closed position. I was able to poke it with a small probe and confirmed it was rubber, but there is not enough showing to take a photo. Not sure if these are original or replaced before I acquired the car. These seals have been pretty much a mystery to me and I'm eager to find out what I can and help where I can to research this.
