Hi guys. Another simple route would be to use Billet Specialties billet aluminum hose separators like this:
They come in many different sizes.
I used 1 inch hose sized separators and I cut one of the "holes" off to mount my front license plate to my front bumper so the plate would swivel back like the original 427 street cars. The center clamping screw holds anything you want onto a round tube. Add a little rubber sheet as a shim if you need to.
Looks like this:
Add a piece of flat aluminum bar to hold the badge and you're done.
Just another idea.
Cheers
