Will this work with my factory mirror housing?

Yes. This lens mounts directly into the OEM bracket—no drilling or housing modification. Just swap the glass and secure with factory fastening points.

Do I need to remove the whole mirror assembly from the door?

Not necessarily. Many owners can access and replace the glass from behind the housing without pulling the mirror off. Check your specific model year to confirm access from inside the door panel.

What prep or treatment does this glass need before install?

Glass ships ready to mount. No painting or surface prep required—just clean the mounting surface on your housing and install.
