It has been a while since last time I removed and reinstalled one, as far as I remember there are 2 blocks of spunge/rubber pads that sit between the removable cowl and the cowl under it. They are located at the right and left ends of the removable cowl. Also, I think there are small plastic clip/spacer things at the aft edge of the cowl (to eliminate rattle) where it fits snug between the windshield trim and the brackets that hold the trim.
