The shaft shouldn't be sliding in the bellows Carl,
after all, that's why it's a bellows.
Mike, if all is straight and nothing is loose then there is no
reason that it shouldn't stay in place. Been ten years on this
one and if I remember correctly, it fit in the toe board hole
rather snug. The rubber mat may help keep it in place also:
