Black an silver plates are only allowed on cars registered 1973 or before. Had black an silver on mine,an it looked well kool as Im all black an silver,but when old bill finally got me after 6 months they werent impressed but managed to talk my way out of a ticket,so all I'll say is that the gamble is yours to take.....and it is a gamble,especially if the old bill are hot in your area !!
