You’ll probably end up making a bracket, but you might take a look at this site. Along with some old stuff, he’s got frames with the plate light, backup light,or third brake light built in. Mostly LED’s. Might save you a step or two.
http://www.taillightking.comEdit. The site worked an few minutes ago, and now it’s a 406 error. Might be down for maintainence.
Edit. Back up, I’ve bought a couple items from him, mostly offshore but all worked just fine.
