Will this mount using the factory grille fasteners?

Yes. This assembly uses factory mounting points, so your existing hardware will work. Just remove the old grille and bolt this one in place using the same attachment locations.

Do I need to paint or prep this before installing?

The grille ships ready to install as-is. The chrome and black finish is applied at the factory. If you want a custom finish or weathering, prep and paint after removal or before mounting—your choice.

What if this doesn't fit or I'm not satisfied with it?

Check fitment against your truck's year and trim before committing to installation. Once mounted, return eligibility depends on condition. Contact support with photos if there's a fit issue before you bolt it down.
