Does this mount directly to my existing mirror housing?

Yes. This glass uses factory mounting points—your current mirror bracket stays in place. Swap the old lens for the new one without touching the housing or wiring.

Will I need fasteners or adhesive to install this?

Check your mirror housing for any factory clips or fasteners holding the old glass. The mounting method follows OE design, so you'll use what was already there.

What if the glass doesn't align perfectly after I install it?

Most OE-style glass is indexable—you can remove it and reposition it if needed. Test the fit before fully seating it. If gaps persist, verify the housing bracket isn't bent.
