2010 Range Rover Sport: The retaining clips that hold in my rear door fixed window have failed. It looks like the clips are glued to the window and the adhesive to the clip has failed. Does anyone have a part number for the clips or is this a replace the window kind of thing and the clips come with the window only? I've tried searching for the clips but the only thing I could find was the window itself. I'd appreciate some direction from anyone who has some insight into this.
