As I recall there were at least four contact incidents the worse of which was on the exit of 11 ending with two cars stuck against the pitwall. This was the longest of the 3 or 4 full course yellows.

Maybe you are talking about the very slight contact between the race leader Shawn Price and 2nd place Kevin Roush in turn 2?

I saw that one fairly clearly; Price braked late and overshot the turn-in - not by much but enough to leave room for Roush who went up the inside. Price tried to come back over and Roush put two wheels over the curbing to avoid him but there was the slightest of contact - right front to left rear and Price spun. KR was lucky a bit to avoid the spinning car and keep 3rd place behind him. Price re-entered 4th and finished in that position.
