Does this bolt to factory mounting points?

Yes — it uses the existing mirror hole pattern on your vehicle. No drilling or fabrication needed.

Will this interfere with my tonneau cover or tonneau frame?

Extended mirrors can catch tonneau edges or frames depending on your cover style and how far it wraps around. Test-fit before securing, or consult your tonneau documentation for clearance specs.

What fasteners do I need to install this?

Mounting hardware is not included. Bring your original bolts or source M-size fasteners that match your factory mirror attachment — refer to your vehicle's service manual for torque specs.
