Door sills at the top maybe? I dunno, they look similiar to each other, right and left hand I'm guessing?
Bottom piece looks similar to a piece I pulled this weekend on my '96 to get to my upper radiator support. I seem to remember it having five holes on one side where it tied into the radiator support and 4 holes on the other side that attached to the fiberglass panel with the Jeep logo above the grille. Radiator support side was tied in with 5 bolts with a 10mm head and a washer sort of thing below the head. The panel side was attached to studs in the fiberglass panel with 4 10mm nuts, also with a washer sort of thing. If that's it, careful putting those nuts in... I managed to break two of the studs off the fibeglass taking them off. Bit of good parts-store adhesive and it was fixed though.
