a paint question for a 66 cuda

As far as I know, the center medallion background is supposed to be blue, and thats the only color it came in.

As for the center grille piece, when I was redoing my car (way back when) I had 3 different centers, so I decided to paint one body color, one the correct flatted black and one silver. In the end, the correct flat black one won the contest, as I am in the school of correctness. I am not sure of the exact protocol, but I believe that flat black was the choice for Formuls "S" cars, but others could have come with body color. Not an expert on this, but I like the flat black the best.

On your car however, since it is already black, I would probably go with body color!! Geof
