Post a photo of your badge, front and back...maybe someone will have an idea! If you find a similar badge on EBay, it may be worth the purchase for the hardware or just configure your own mounting hardware. I was just about to post an inquiry regarding views re grill badges, particularly on vehicles that have not yet reached classic status or mileage milestones. I just purchased a badge that came with mounting hardware. Will have to design some cushion so that it does not damage the grill.

I think that you’ve got it! Depending on your grille, the cross member maybe necessary...it was for mine with the louvered grille.

I would think that some sort of protective coating would be in order. My RAC badge has an enamel finish, so it should endure.
