Do the factory mounting brackets bolt straight on?

Yes. This assembly uses the stock mounting points — no drilling, welding, or fabrication needed. Use your existing hardware and fasteners from the original grille.

Will I need to prime and paint this before installing?

That depends on your finish preference. If you want color-matched results, plan for prep work and paint before bolting it on. The composite surface accepts primer and paint cleanly.

What if the headlight opening doesn't align perfectly with my bulb housing?

Test-fit the assembly on your vehicle before committing to fasteners. If minor gaps appear around the bulb, you can shim or adjust the mounting slightly at the factory points. If significant misalignment occurs, contact support with photos.
