Do these bolt to factory holes or do I need to drill?

They mount at factory rocker points — no drilling needed. Existing attachment locations line up directly.

What hardware do I need to install these?

Mounting hardware is not included in the package. Verify bolt size and specs against your vehicle's factory attachment points before installation; fasteners are typically standard metric hardware available at any hardware store.

Can I paint these to match a custom color?

Yes. These arrive in black finish and are paintable. Light sanding and a quality automotive primer prep will help any custom paint adhere properly.
