Will this glass fit my existing mirror housing?

Yes — this is a direct optical replacement. The glass mounts at factory attachment points without modification to your mirror frame or backing plate.

Do I need to remove the old glass to install the new one?

You'll need to extract the existing mirror glass first. The mounting tabs align with OEM slots, so installation is straightforward once the old unit is out. Use care to avoid cracking the old glass during removal.

Can I use this on the right side if I need to?

No — this is cut and oriented for left-side (driver) mounting only. The curvature and attachment points are specific to that position. Order the right-side version if you need passenger-side coverage.
