Well I have been restoring my car starting at the back. Car is a 67 Buick Sport Wagon. The issue I have come across is the glass is loosening at the chrome mount on the bottom. Someone tried filling it with clear silicone to stop the leaking and tighten it up, but it's no good. Anyone have any suggestions on how to firmly reattach and seal this? I could take the tailgate apart for some pics if it would help. Maybe someone has dealt with thus before?
