Do I need the right-side bracket too?

Yes. This is the left bracket only. Both sides work together to hold the bumper cover square. Order the matching right bracket to complete the job.

Will this work with a damaged bumper cover?

This bracket supports the cover, but it won't fix cracks or dents in the cover itself. If your cover is cracked, replace it first—the bracket mounts to solid plastic.

What fasteners do I need to bolt this on?

Factory mounting points are pre-drilled. Confirm your existing hardware during removal—you may reuse the original fasteners if they're intact. Have new hardware on hand in case any bolts are stripped or bent.
