Windsheild trim.....Lines up with these holes. Start with one hole on bottom, one on the side and one on the top. This will hold every thing still. Don't tighten all the way so that you can line up other holes if need be. Center strip causes my tourette's to act up. Insert middle screw through inside trim. Don't forget to put the clips top and bottom that cover the ends of the windsheild molding. Insert through the rubber center. From outside line up the stainless with at least one screw, I find the top works best. Gently start the screw from inside. Don't forget to install the mirror bracket on the second hole from the top. Line up the remaining screws, then tighten down.
