Will this mount directly to my Durango without drilling or brackets?

Yes. This mirror uses factory mounting points — no new holes or custom brackets needed. Standard fasteners secure it to the existing door panel location.

Does this come with all the hardware I need to install it?

Mirror assembly is included. Confirm your existing fasteners are in good condition before install; you may reuse them if they're not stripped or corroded.

Can I swap this from left to right, or does it only fit the driver's side?

This is a left-side mirror only. The glass angle and mounting ears are curved for driver-side fitment. Order a right mirror separately if you need both sides.
