Slack in steering shaft

First, you have to sign up on the web site you referenced to be able to view the picture. See if you can save that image to your computer and then add it to your post here as an attachment.

Second, you are missing so many major components, it might make more sense trying to locate another column. You will have the slop until you replace most all of those missing parts. The spring-loaded rear third of the housing with the "depress lever to remove key" is just that... with all the locking hub and other parts installed, you really do have to press the lever down toward the floor so you can remove your key - it leaves the steering wheel locked for anti-theft purposes (more modern cars began using buttons, etc. you have to press).

You need to find someone with a discarded column they won't mind gutting for you (rendering theirs useless) or replace yours completely. To be honest, I have not seen a column for a floor shift car, but it doesn't make sense to have the gear select indicator on the column - its on the console where you actually change gears. Maybe someone with an original can post pics.
