I think the top picture is the little plastic straps that hold the seat belt to the seat box, and the bottom picture looks vaguely like the bottom half of the old thule rack brackets for the factory half basket on soft tops.
Ahh. That makes sense. I repaired the seatbox with the YRM panels and obviously didn't drill the new holes. Could someone post a picture so I can see roughly where they go? I threw away the old seatbox side panels.
