Will this glass fit into my existing mirror housing?

Yes—this is OE-profile glass designed to drop into your factory mirror frame. No drilling or modification required.

Do I need to remove my old mirror from the car to swap the glass?

Typically no. Most mirror glass can be removed and replaced while the mirror assembly stays mounted on the door. Your service manual will walk you through the exact process for your model year.

Is any adhesive or hardware needed to install this?

This is a glass-only lens—it seats into your existing mirror housing using the factory retention method. No additional adhesive or fasteners are included or required.
