It's just hardware. I doubt your Jeep is gonna go Stephen King "Christine" on ya. You could get a dead mans walker or wheelchair from hundreds of VFW's around the country. Legally speaking, don't advertise!
Not really my style, but I don't think you are gonna be struck by lightning over it. I'd be careful how much you flaunt it around to strangers. I can just imagine you and the crematorium on a local 10:00 news special report.
