Wonder of this is going to be a early/late 67 production change, just like the metal or rubber front bumper fillers.
For the 67 guys that posted, what's your build date? I believe my 67 is early. I think mine might be built in may, but I'll double check.
My 67 got whacked at some point in its life. It's original 400 and had non 400 hood, bumper and grille on it when I bought it. I also found both metal and what was left of rubber bumper fillers. I believe the metal bumper fillers are original to my car and the rubber fillers came when some one swapped a non 400 front sheet metal.
