   1. Using a measuring tape, measure the distance between the windshield pillars from the base of the shade line.
   2. Using a marking pencil, halfway between the windshield pillars, draw a centerline (1) on the windshield from the roof panel to the windshield base.
   3. Draw a perpendicular line intersecting the centerline (2) at that location.

      The top center of the mirror mounting base will be at the intersection of these lines.

2. Scrape the inside windshield thoroughly with a safety razor or utility knife in order to remove all old adhesive.
3. If reinstalling the original mounting base, place the mirror mounting base in a suitable holding device, such as a vise.
