Do these need to be painted before installation?

Finish state is not specified — confirm color match and surface prep with your installer or body shop before committing to bolt-down. Many buyers paint to match or prep for protective coating.

What hardware do I need to mount these?

Fastener spec is not confirmed in product data. Hardware is not included — source bolts, washers, and lock nuts rated for panel-to-body attachment before installation begins.

Are these designed for bolt-on installation at factory holes?

Factory mounting points are confirmed. Installation uses existing body attachment locations — no drilling or custom fabrication necessary at those points.
