I'm new to the forum - Ibought a wind deflector from an EBay volvo parts guy - need some help attaching it to the sides of my car - the little metal "slider that comes out of the deflector lines up perfectly with the little holes in the sides of the back seat - but the holes are round and the slider is flat and doesn't go in - Obviously there's a hardware piece missing between the metal slider and the hole in the back seat side panel - Any ideas
