There were a couple metal type "spacers" on my 52 panel. From what I could tell it seems they went where the windshield defroster slots are cut in the trim/moulding. It will keep you from tightening the screws there and caving in the trim.
......I'm probably wrong but just my guess and that's what I did with the ones I had.
EDIT: I'm all wet here....miss read the question. Disregard my comments! sorry
