usually the alignment post break cleanly. put the 2 pieces together and eyeball how cleanly they meet. if the break is nice and tight when put together,JB weld the 2 halves together making sure that the post is absolutely plumb or level,whichever one applies. after the JB has dried,mix up another batch and neatly "puddle"around the base of the break. that should complete the repair. it has worked for me in the past and still going strong. JB is your friend.
