Will this grille mount at the factory attachment points?

Yes. This grille mounts directly to factory rocker and frame points with existing hardware — no drilling needed.

Does the chrome finish need prep before install?

Wipe down with a clean cloth before bolting on. If the surface has been in storage, a quick rinse and dry is all you need.

What if the grille doesn't line up perfectly with my bumper opening?

Test-fit before fully tightening all fasteners. If gaps appear, loosen mounting hardware, adjust position, then secure. Factory fitment should be flush, but a slight adjustment is sometimes needed depending on your vehicle's condition.
