Need a little help about lower windshield glass & molding on a 68 Dart GT

Hi Guys,

I am wondering if anyone else has noticed this with their Darts - my Dart doesn't have the windshield in yet and I am trying to figure out how the lower windshield chrome molding attaches ............ there are no "nibs" on the inside edge of the cowl panel to put "clips" on and the pinch weld that surrounds the other three sides within the windshield area is not on the lower part of the cowl panel ......it only has four little ( about an inch in length) stamped out little "notches" in that cowl area - how does the windshield weatherstrip attach and how is a person suppose to snap on the chrome molding at the bottom edge of the windshield once the weatherstrip & glass go in?
I'm due to take the car to the interior shop for the vinyl roof & headliner & windshield & rear glass installation and I need to know if I have to drill holes for the clips to hold the chrome molding.
just a note - when I took out the old windshield, the entire bottom edge was glued in along with the bottom chrome molding & not done well at all !

Thank you for any help you can give
