I have figured out much of it from looking at the front and back pictures of the part, the pics I posted earlier from the rally car website, and from a couple of videos about replacing the ignition lock. Some pictures of the upper bearing area might be helpful, as well as a description of how it comes apart and goes together.
The guy I talked to said something about the steering column being spring loaded to hold it in place.
I got sidetracked this weekend when I had to rebuild my washing machine, but I'm about to order the part. I think I will go with the cheaper one and move my stuff over from the existing part. I need this to go smoothly since it is my only functional car and I don't have time for stuff to go wrong, so I may buy the instructions. Maybe we should split the cost of the instructions since we are doing the same thing...LOL!
BTW, th videos show that regular torx bits won't fit...they are some sort of security type with a hole in the middle. Maybe everyone else already knows this, but I would not have been happy to discover that part way through, so I thought I would mention it!
I bought this to fix a microwave and ended being quite useful for the neon. It includes all the torx that will need for this job. Stupid cheap too:

Download the service manual if you haven’t already for instructions on removing the column:

I did not use a steering-wheel puller to remove the wheel. I gently tapped it with a rubber mallet and pulled gently. Careful not to hit yourself on the face as I did when it suddenly released.
There is also a large pin to remove and reuse. The column is spring loaded but that is best released once you remove the column.
The more expensive housing is for an auto transmission. You will have to mod anyway so in my opinion, it is not worth it.
I originally bought kit 5159136AB thinking that it had everything, but as I know now, it did not include the bearing because it is not serviceable, and it does not include the housing. This kit would be useful if your column rod is damaged.
