Do these mount at the factory hole locations?

Yes. These mirrors use factory mounting points — no drilling or custom brackets needed. Install uses existing anchor holes on both sides of the truck.

Will these mirrors clear my tonneau cover or bed accessories?

Mirror extension varies based on your specific setup. Test-fit before final installation to confirm clearance with any tonneau cover, toolbox, or bed-mounted gear you're running.

What hardware do I need to bolt these on?

Mounting hardware not included with this assembly. You'll need fasteners rated for your vehicle's mirror mounting points — check your service manual for the correct bolt size and torque spec.
