Does this grille mount at the factory grille opening?

Yes — this assembly uses factory mounting points, so no drilling or frame modification is needed. Bolt it in place using your existing hardware or fasteners of the same size.

Can I repaint this chrome grille, or does the finish need to stay as-is?

Chrome is already finished. If you want a different color, you'd need to strip the plating and prep the base material for primer and paint — a job for a shop with proper equipment. Most keep it chrome.

What if the grille doesn't line up perfectly with my truck's front end?

Test-fit it first before final assembly. If gaps are uneven, you may need shims or slight adjustment to mounting tabs. Factory tolerances vary truck to truck — check alignment before tightening everything down.
