1969 Dart Convertible Windshield lower trim

I never had an issue not "locking the lower window seal gasket. Yes technically it gets "locked" by this inserted piece of plastic in the gasket groove.....but in my case and many others ..never a leak never a loose chrome strip never an issue. looks great!
Its not GLUE....its called BUTYL and its used in modern window install. a few dabs in choice places and never an issue.
Installing the window clips for the chrome like on a hard top may or may not work with the convertible window gasket.... Bottom line is, been done for years by many no issues and by the sounds of it his car already was converted to chrome metal strip.
