Steering column teardown

I am tearing my manual column down to clean and paint, but I can't figure out how this piece comes off. Any suggestions?

I have removed the shaft and outer tube already. That piece circled in red seems to be what is hanging up.

Also, I got the rebuild kit for the coupler, but now am wondering if the universal joint is a better option. Thought on that?
