Having had a rummage about in the dark....
I have a complete ( later ?) sunroof window, tinted glass about 36x75. This is the one that opens with a rotating handle. Seems to have a flexible grey plastic piece of trim ?
I also have an ( earlier ?) version, less glass, that opens with a lever action handle, glass about 39x75. This has a harder black plastic trim - but most of the small white L shaped studs inside it are mising (snapped). The glass was used to repair my roof, from an '89 CSW.
Not sure how much use to you the plastic trim will be without the clips to hold it ?
