I dont think so. Never seen it before, either.
Would be interesting to see...
I haven't seen the "Challenger" emblem in red but it would look cool if you car has a modern/custom touch, IMO.
The hood call outs, at least for "340 Four Barrel" look cool red with black outline so the Challenger emblem I think would look cool as well.
Not too hard to do. I would scuff up the chrome to let the paint adhere better, spray paint gloss black to coat the whole emblem then use a brush for the red. Get the brightest red without going flourescent
