I got the complete door seal kit from classic parts. How do I attach some of the molding? Like the glass u channel. It doesn't have the clips on it like the original has. wasn't sure if I was suppose to screw it on or what. Also there is a piece that goes on the inside metal trim that is stapled on??some of it I know has to be glued on and they sent the glue for that. I'm getting tired of seeming daylight thru the door and the cab leaks cold are in like a barn door.
