AJ, welcome to Automotive Forums..
head to jeep dealer.. a plastic 'sleeve' or overlay has to bolt, slide, or snap onto
that for your plate to bolt to..
you might try pep boys, or autozone; whatever auto store you've got close..
they might have a universal type that you could bolt or clamp to your front end,
and they might only be $7-15, as opposed to the Jeep one at stealership; probably
$35-50 for a plastic plate holder..
hope this helps..
