Does this bracket come with fasteners or do I need to buy mounting hardware separately?

This is the bracket only. You'll need to source OEM or compatible fasteners to mount it. Check your vehicle's service documentation or the fastener spec from your local dealer before ordering hardware.

Can I reuse my old bumper cover with this new bracket, or does it need to be replaced?

The bracket is independent of the bumper cover fascia. If your existing cover is undamaged and fits properly on the new bracket after alignment, you can reuse it. Test-fit before final assembly to confirm gaps and fitment.

What's the difference between this right-side bracket and a left-side one?

The bracket geometry is mirrored. Left and right are not interchangeable—this one is engineered specifically for the right side of the vehicle. Using the wrong side will result in misalignment and fitment issues.
