87810A MIRROR ASSY INNER REAR VIEW, NO.2.
FWIW I added the mirrors. I did a swap with a member that wanted the speaker grilles. My impression is the mirrors do work. The 'downside' is the mirrors do require "purposeful intent" to gain useful information. If you train yourself and choose to use them they are very helpful. I like them, am glad I have them and
I would do it again. They are a neat 'old school' trick that works. They are not a high-tech, super-intuitive, awesome electronic display. If your expectations are reasonable you'll like them IMHO.
