Will I need fasteners to install this bracket?

Fasteners are not included with this bracket. You'll need to source bolts that match your factory mounting holes — check your OEM service manual or test-fit the bracket against your existing hardware before removing the old one.

Does this come with any primer or finish?

The bracket comes as-is in raw material. If you're painting to match your bumper, sand and prep the surface before applying primer and topcoat.

Is this bracket for the left or right side only?

This is the right-side bracket only. If you need both sides, order the left-side bracket separately.
