Do I need to drill or modify my bumper to install this?

No. This bracket mounts at factory attachment points—everything lines up stock. Basic hand tools and a socket set get it done in under an hour.

What hardware do I need to bolt this on?

Fasteners are not included with this bracket. Check your vehicle's service manual or OEM parts diagram to confirm the bolt size and torque spec for your specific model year.

Can I paint this bracket, or does it stay hidden under the bumper cover?

It stays hidden behind your bumper cover, so painting isn't necessary. If you prefer a finished look for any reason, standard automotive primer and paint will adhere without prep work.
