steering shaft pin

68 barracuda, installed 318 engine, trans, headers up from bottom. When steering column came in contact with steering box, it didn't line up as I was doing this myself, forgot to view when lowering body to k frame. Removed steering column into drivers area and out of vehicle. New coupler kit coming in a few days, while viewing this, I noticed this black plastic pin sitting in silver area of column, looks like it was snapped off there. Any help as to what it is for, do I need to buy a rebuild kit for the column, if so, what should be ordered. I have viewed a 35 minute video, "hshaftcoupler1.jpg shaftcoupler.jpg shaftpin.jpg ow to rebuild a mopar a body steering column" but nothing mentioned, TIA..
