The reproduction weatherstrip starting at the quarter window has 3 threaded studs with nuts and star lock washers attached, the separate attaching nut and bolt package from AMK for the quarter window has three rubber washers that don’t show up on the assembly manual, it only show’s a washer before the nut goes on which doesn’t make sense. A rubber washer would be squeezed out if put on there, I could see one between the weatherstrip stud and body to maybe seal it off but the assembly manual doesn’t show that. Any thoughts?
