hello. i am rehabbing my hard top and trying to be sure i have all of the necessary components. i will likely update the post as i go, but, at the moment, there is one part for which that i can't find descriptions or diagrams. it's the bracket that mounts to the front underside of the fiberglass roof (by rivets) and bolts to the top front side of the windshield frame. anyone know what this is called and where i can get one? thanks!
