Mark, I have heard of but not been witness to broken leafs in the beam. If you were to have one or more broken leaves, that side or both would sit lower and possibly cause the tire to rub.
There is a thread here with instructions and pictures as to how to remove some leaves.
The procedure for replacing broken leaves would be about the same. Changing to longer shocks is not a good idea as it would severely affect the ride quality.
