'94-97 Windshield Trim Insert Details
The top trim (Left in the photo) has both a hard plastic "seal" slid into it, and a self-adhesive foam strip ~1.5" long x 3/8" x 3/8" in the corner. The side trim (not shown) has only the seal. The bottom trim (Right in the photo) has only the hard plastic retainer clips, each held captive by crimps in the lip of the trim.
The seal wraps under the Aluminum trim to keep the metal from contacting the glass.
Earlier trim ('80-93) might have less in the top & side pieces, but the bottom clips are identical for all '80-96 & '97 heavy. Their main tabs go toward the front (bottom).
