CC Clue: Who Exactly Won?

I’m still trying to determine who to give the win to, for the ’77 Bonneville. Mr. Tactful might have, saying it was a Bonneville, and referring to his Mom’s former ’78. Carmine was mighty close, calling it a ’79 Bonneville.  Sean also almost nailed it, with a guess of a ’77 – ’79 Catalina or Laurentian. None were exactly on the money, but then this emblem and C Pillar may well have been used for more than one year. So you’re all winners. It’s as close as I can get too.
