Will this fit my passenger mirror, or is it driver-side only?

This is driver-side left only. Passenger-side mirrors have a different curvature and mounting orientation. Check your mirror position before checkout.

Do I need any fasteners or adhesive to mount this?

The glass seats into your existing mirror housing using factory mounting tabs. No additional hardware or adhesive is needed—it's a direct swap.

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

Minor gaps at the edges are common when glass ages in the housing. Gently apply pressure around the perimeter to seat it fully. If it rocks or feels loose, inspect your mirror bracket for wear before reinstalling.
