To get the ball rolling here is my preliminary idea:
I included my inspiration just in case someone didn't pick up on it. I thought the center of the Utah outline might be able to use a little something, but I also don't want to over-complicate it. I can also make the black outlines silver (chrome-ish) to more accurately simulate the original badge, and help it stand out on dark tinted windows or bumpers or bodypanels (except the titanium body).
I put the text Utah Cruisers and left off any images of an FJC because I am of the opinion that our "group" should not be a super exclusive club that you have to jump through all these hoops to get in or act or dress a certain way. I say as long as you wear pants or similar and you have a "rig" to put the decal on (or at least a trapper keeper or whatever) and most importantly you show up to some event(s) you're in. If you are in a Jeep great, Nissan sure, Fiat, we'll talk about it. Just bring your friends I say.
Feel free to vote me down though. This country is a democracy, (or republicarocity

).
