Will this fit my factory mirror housing without any work?

Yes — it's designed to drop into your existing bracket and housing. No drilling, cutting, or frame modification needed. Just verify your mirror frame is straight before installing.

What fastening method should I use to secure the glass?

Mounting method isn't specified — test the fit first, then decide between automotive silicone adhesive, clips, or fasteners based on your housing design. Some factory housings use retention tabs; yours may vary.

Can I order the right side mirror glass separately?

This is the left (driver) side only. Passenger mirror glass is a separate part — order it individually if you need both sides replaced.
