Original Windshield Molding off of a 1963 2 Door Hard Top Pontiac Catalina! This is the Left Section of the Lower Windshield Trim that connects to your A Pillars and encompasses the windshield. Good shape, no bends or dents, just some minor surface rust on the inside, see pictures. I am not sure if this fits the Grand Prix or Bonneville, but it might! Please let us know if you need any more details.
