Does this glass come with mounting hardware?

Just the glass lens itself. You'll use the existing fasteners and clips in your mirror housing—inspect them before installation to confirm they're in good shape.

Will this fit into my existing mirror housing?

Yes. It mounts at the factory attachment points with no drilling or frame modification needed. Test-fit it before finalizing any fasteners.

Do I need to paint or prep this before installing?

The lens arrives ready to install—no paint or primer required. If your housing is a different finish, you may want to match the back side, but the reflective surface is production-ready.
