The installation has begun.
The stock mirror has a base that has 2 functions. 1) It supports the mirror. 2) It secures the ends of the sun visors.
The new mirror is attached to the windshield. I still wanted something to hold the sun visors in place so I cut the stem from a unit with a bad mirror. I thought it would look a little better with some texture to it, so I spritzed it with some rubberized undercoating.
