Do I need fasteners to install this, or does it come with hardware?

Fasteners are not confirmed as included — source M6 bolts or equivalent hardware that matches your factory mounting point spec. Test-fit the bracket before finalizing hardware choice.

Will this bracket work with my existing license plate frame?

Yes. The bracket mounts the plate itself; any frame you're using attaches to the plate independently, so there's no conflict.

Is any prep or painting required before installation?

No prep needed — this bracket arrives ready to bolt on. The finish is designed to resist corrosion without additional coating.
