Well, since I started this and everybody has contributed so much, I figured I better dig out my books and try to do some of the dirty work. The little information I have just concours with what has already been said though, so I'll just post a pic. The photo says " Don Yenko at Sebring in '65". Check out the truck running lights on the roof!
