I picked up an Evel Knievel at Allentown. I am not familiar with how the front of the backbox sits on the main portion of the backbox. The hinged frame is hanging a little low and not flush. The hinge is tight, but the metal pin that is attached to the frame is loose and the hole it goes into on the front of the backbox has become oversized. Should there be a metal plate to receive the pin or does it just fit into the frame. I can't seem to find a replacement online. Does anyone know a part number or who sells them?
