I have a 61 Impala that I have been working on for the past 25 years. I finally got the paint and most of the trim back on the car, but I have several questions regarding the installation of the windshield. I found all the trim for the interior and exterior that goes around the windshield; however, I cannot find any supplier that sells the clips for the top of the exterior molding that goes across the top of the windsheld as well as if the exterior side molding requires any clips. It appears that there should be 3 on each side, but I cannot find anyone that sells these clips as well. Also, is there any seals that are required between the windshield, frame and moldings? I have the gasket that goes around the windshield, but no seals otherwise. Also, can I install the windshield and install the molding clips later? Any help would be great appreciated.
