These foam fillers are often lost, and may have only been used on high-trim trucks. The plastic face is fairly robust, but the adhesive between it & the foam doesn't last. Note that the fillers are punched L & R near the bottom. Modern automotive spray adhesive (like 3M 66 or 77) can be used to re-attach the clear facings to the foam.
