I'm not seeing Nick Marco's #83 sedan, but here's two more photos from the same batch provided by John Mosher that I think are in the picture above - I know who's in the #0 (or as was mentioned on the board previously as the "square nut"), but I don't know who is in the #55C:
As for the other cars in the picture, I'm not sure about the big blue Falcon up front, or that other red/orange coupe on the outside near the rear. Also not sure about the red Pinto(?) in the middle, unless that's the one that Rick is identifying as an early Joe Coverdale #J9. I remember Joe's cars were red before he went with the black and silver paint scheme that he carried throughout the 80's.
As Rick mentioned, the black and gold car is Dave Spurlin's first car. It's a former John Chemidlin #747 coupe.
