Camshaft or Distributor broke?

the distributor is held in place by only 3 bolts, 12mm i believe. pull them and remove the alternator. see where it went wrong. the distributor would be the easy fix. it is not a gear driven dist, it is a slot and key way. it can only go in one way. i had 3 hondas and replaced them on at least 2 of them.
