Will I need to drill holes or modify the bed to mount this?

This assembly mounts at factory points, so no drilling or bed modification is required. You'll work with existing bolt holes and attachment locations.

What fasteners and hardware do I need to install it?

The assembly itself is included — hardware for final mounting is not confirmed in the product specs. Verify your truck's factory mounting hardware before installation, or source standard bolts rated for your truck's weight capacity.

Can I paint this black finish, or does it need any prep work first?

The finish arrives ready to install as-is. If you plan to paint or refinish it later, treat it like any hard panel — light scuff and prime before topcoat application.
