I have sets of factory windshield trim for the '60-'63 and the 4-5-6 style, including the factory clips. The rubber windshield grommet is not made with the stainless steel windshield trim in it. When installing, put the trim in the grommet and then put the rubber on the windshield and then install the windshield.
I found a auto glass shop in my area that will furnish and install a new windshield, including removal of the old windshield & rubber and dispose of it, for less than a new windshield from LMC or Classic Parts costs. They also guarantee the installation.
