Steering Column Collar Install

Hey FABO, hope 2020 is off to a great start for all! This is probably an elementary question, so apologies in advance.
I'm reassembling my steering column and am looking for some expertise.
1970 Duster, floor shift steering column, connected to Borgeson box.
What I would call the third collar (not the first collar with turn signal switch, not the second collar with ignition switch) is my issue.
How is it secured to the large steering shaft column jacket tube? On page 19-38 of my FSM it mentions bending some tabs. There was nothing there when I dis-assembled, so I'm not sure what that is. When I install the 4 screws through the second collar (with ignition switch) into the little bosses on the column jacket, it does hold the third collar in the right position but there is still movement and slop in the third collar.
Is there something missing with tabs on it?
Thanks for any input.
