Will this bolt directly to my truck without drilling?

Yes. This mirror uses factory mounting points — no drilling or modification needed. Line it up and bolt it down.

Do I need any fasteners or hardware to install this?

The mirror assembly itself is included. You'll need to source mounting bolts if you don't have them on hand — check your truck's service manual for the correct size and torque spec.

Is the glass adjustable, or does it move on a hinge?

Manual adjustment means you physically aim the mirror by hand before tightening it down. Once set, you reposition it by loosening, moving, and retightening — no motors or cables.
