Gordon Johncock, Rick Mears go head-to-head (1982)
With 12 laps to go in 1982, Gordon Johncock led by 11 seconds over Rick Mears, but the handling on his race car started to give way. Mears charged after the race leader, cutting one-second a lap off his lead until the two cars were nose-to-tail with two laps to go. Mears nearly passed Johncock in the first turn on the white flag lap before Johncock closed the opening. Johncock held on to win by .16-seconds -- at the time the closest margin of victory in Indy 500 history.
