I was looking under the truck and noticed that a nut was missing. It is located under the truck and connects the the floor shift for the 4c4 that connects to the tranny….was nut or clip is suppose to go there

 

This was the toughest question on the F150 forum I guess, but I figured it out

 

are you gonna keep it a secret ?

 

You are just missing the grommet
Ford parts used to sell them and probably still do
Put the new one in the metal bar / link, then squeeze it onto the transfer case shift lever using big channel lock pliers
