Do I need new fasteners to bolt this on?

Check your existing grille fasteners first—many reuse the stock mounting hardware. If yours are rusted or stripped, bring them to a hardware store and match the bolt size and thread pitch.

Is this chrome finish already ready to install, or do I need to polish it?

It arrives ready to bolt on. The finish is sealed and shouldn't require any prep work before installation.

What if this doesn't fit my grille opening?

Test-fit before final fastening. If gaps appear around the edges, you may need to shim or adjust the mounting brackets slightly. Trim fasteners flush once positioned.
