Will this mount using my factory bolt holes?

Yes. This bracket is designed for factory mounting points on the Titan front fascia and requires no drilling or additional frame work. You'll use existing holes or studs already on your vehicle.

Do I need hardware, or does the bracket come with bolts?

The bracket ships as the assembly only. Confirm the size and type of fasteners needed for your specific vehicle by checking your owner's manual or test-fitting the bracket before final installation.

Can I repaint or customize the black finish?

The powder coat is already applied and cured. If you want a different finish, light sanding followed by spray paint or powder coat will work, but the base finish is ready to install as-is.
