Do I need fasteners or hardware to bolt this on?

Mounting method not specified — test-fit your bracket against the factory points before committing to fasteners. You'll likely need bolts matching your OEM setup; bring your old bracket or check your service manual for torque specs.

Will this work if my bumper has sensor or fog light cutouts?

This is a structural bracket—sensor holes and light openings are cut into the bumper itself, not the bracket. As long as your bumper is intact, the bracket installs behind it without interference.

Should I prime or paint this before installation?

Depends on your finish preference. If you're repainting the bumper assembly, handle the bracket during that job. If you're keeping everything as-is, the bracket stays hidden behind the bumper—paint is your call.
