Need HELP with tilt column assembly issue

[ScottH]

I am working on a tilt column from an 89 Blazer that was extremely loose.
Took it apart ok & tightened up the bolts, but a part fell out that I am having a problem reinstalling. I have looked over several videos as well as online tutorials on how to do this, but none mention this piece or how it goes back in.

The first 2 pics show where I am now with it. The 3rd is the part, and the 4th kinda shows about where it goes.

If anyone can shed some light on this I would REALLY appreciate the help.
I need to get the column reassembled as soon as possible.

Thanks very much.
Scott
