By how much did Hamlin beat Busch by in the Budweiser Shootout (I know that Busch was given the win, though)?

Hamlin was penalized and so Busch was given the win, but Hamlin crossed the line before Busch, and I want to know how close that was. It looks like it would be no more than .002 seconds. If Hamlin hadn't been penalized, that might've been the closest finish in NASCAR history, but I want to know what the margin actually was. Thanks!
