'67 cars used brite-lock plastic that snaps into the rubber windshield seal, locking it in place. The stainless steel corners slide onto the brite-lock. Its reproduced and the front windshield isn't too difficult to install. Mitchells (now sold to someone else), and Year One are two places I know that carried it. Search YearOne, ebay, mopar megaparts, places like that for '67 lockstrip.
