How far can you go when restoring a SSP in NC?

[BarryBum]

I am wanting to restore a SSP Mustang back to the original NC black and silver paint scheme. I am planning on doing the state trooper and state seal on a magnet so they can only be applied at shows. I am wanting to know how far I can go without crossing the impersonating an officer line. I would like to do the wig wags, strobes, antennea whip, and fake (old) radio and scanners. I called the NC attorney generals office today and I am awaiting a return call in hopes that some of my questions will be answered. How about you guys, what can ya'll tell me??
Oh yea, new guy here....from Western NC.........glad to be here....
