Looking for a pic of the quarter window "rear auxiliary seals"- https://pontiworld.com.au/usgmsp/product_info.php?products_id=6242 Im thinking these fit on the rear side of the quarter window by the pinch weld. I think theyre held in place by two screws that are diagonal from each other Thanks!
Those are similar to what I put on my car. They are held by 2 screws diagonally. I think the L shaped tab was different on mine a little than your pic. They fit like a U with the curved part like wrapped around the window. I'll look for pics. I can't remember if mine are Metro or Soffseal.
