I think it depends on the fuel tanks---if there's drop tanks, have the bombs outboard like Rdenham said. But if there's nothing on the inboard pylons, I think the bombs are more likely to be inboard. (I have pics of both configurations, and outboard bombs are far more common----the inboard position only appears when there's no drop tanks)
PS--when I first saw this thread, I thought it was going to be a question about the fuselage rails.
