[quote=Wolfman]I agree with Golfdad here. As long as the old ball and castings are in good shape it isn't absolutely necessary. One caveat though, when stepping the mast you will want a someone holding the mast step on the ball so it won't pop off. This person should be positioned to the side of the mast so they don't get skewered if the mast pops off (common sense I know). Some people have also gotten away with tying the mast down to the front beam to hold it in place. Once the old one breaks or the ball wears out you will need to upgrade.
