- Determine the location of the mirror mounting base by marking
 the outside of the windshield with a wax pencil where the base was previously
 located. If it is not clear where the base was located, use
the following steps to determine where the base should be installed:
 
| 1.1.  | Using a measuring tape,
 measure the distance between the windshield pillars at the windshield blackout
 line. | 
 
| 1.2.  | Using a marking pencil, halfway between the windshield pillars,
 draw a centerline (1) on the windshield from the roof panel to the
 windshield base. | 
 
| 1.3.  | Draw a perpendicular line intersecting the centerline (2)
 at that location. | 
 
The bottom center of the mirror mounting base
will be at the intersection of these lines.
