It was mentioned earlier in the thread, but to prevent rehashing the issue, the hollow pivot bolt necks down internally and can accept the lockpin fairly snugly.
But - the 777 has this exact same configuration, with a hollow pivot bolt right next to the lockpin location. (Sorry, can't find a good photo online.) I'm curious why this has not been an enough of an endemic issue on the 777 to issue an AD. There have certainly been inadvertent 777 nose gear retractions that you can find on Google.
