Do I need to buy bolts separately to install this bracket?

You'll want to have standard fasteners on hand. The exact bolt size and count depends on your vehicle's factory setup—pull your existing bracket or consult your service manual for the spec.

Will this bracket work if I'm replacing just the bumper cover?

Yes. If your original bracket is damaged or missing, this bracket mounts to the same factory points and secures a replacement cover just like the OEM part would.

Should I prep or paint this bracket before installation?

The bracket is ready to install as-is. If you want it to match your bumper color or protect the finish, light sanding and a coat of primer before paint will prepare the surface.
