Does this glass come with a backing or adhesive pad?

The assembly ships as a complete lens unit. Confirm the mounting method with your vehicle's mirror housing before installation — backing type and adhesive are not specified in the product data.

Will this work if my current mirror glass is cracked or missing?

Yes, this is a direct replacement. As long as the mirror housing frame itself is intact, this lens mounts to factory attachment points without modification.

What if I ordered the wrong side by accident?

Contact support to confirm return eligibility. Always verify you have the correct side — left and right are not interchangeable.
