Steering column

[Mark D]

In the process of rebuilding my steering column on a '72 lowlight and I'm getting more and more confused as I go. Seems I've got 3 options for the top bearing.....
  

This is what came out   :

   

and this is what I was sold as the correct bearing

   

Neither of which look anything like the parts diagrams I have seen which have a flanged bearing and long thrust ring. 

   

Can anyone enlighten me to the correct option? Grateful for any help,
