65 b'cuda windshield install--help!

Dear all: My 65 barracuda windshield and rear window has been replaced and PARTIALLY secured (new Precision rubber surrounds). The specialty help I had is unavailable. I know there is something further I need to insert to complete the installation to be road safe. I don't know what to call the part in order to order it. It is some sort of retaining hardware. Can anyone advise on next steps and proper terminology when ordering? Many thanks, J
