Do I need special fasteners to mount this, or does it use the factory bolt holes?

This valance mounts at the factory attachment points on your bumper frame. Verify bolt hole alignment during test-fit before final installation — hardware type depends on your specific mounting configuration.

Can I paint this right away or does it need prep work first?

The primed finish gives you a clean base. Sand lightly with appropriate grit, wipe clean, and you're ready for primer and topcoat. Exact prep method depends on your paint system — follow your specific primer and paint product instructions.

Is this a direct drop-in replacement or will I need to remove the old valance first?

You'll need to unbolt the factory valance before installing this one. It replaces the original panel completely and uses the same mounting location.
