Ah yes, wrong paint application. Much like a 66 500 vs 66 440 grill.Coronet 500 grill had that satin black area in it, as did the headlight bezels. The bezels had horizontal bars on them that mated up to bright horizontal bars that bolt to the dark area of the grill, bisecting it. The grill also had a specific "500" centre piece that joined the horizontal bars. Not the first time I have seen this grill on an R/T, and likely will not be the last.; but it is incorrect.
