Steering Column Question

So I have a couple of things that I am needing help with. The first is when I was taking out the upper bearing insulator it all came apart. I did a quick search for a new one, and it looks like these are not being made any more. Does any one have any idea where I would be able to find one?

The second part of this is I am trying to get the two housing off. I am not sure what to do next in order to get these off. Any help would be greatly appreciated.
