That looks like a van tilt column..they are longer than a truck column..The fix: Drill the plastic rivets from the shaft,collapse it and bolt it in but unless someone else has messed with it,the grommets,neutral saftey,and wiring will have to be modified.I know what that little shaft is you are talking about,on the vans it goes from the column down a few inches to the rag joint on the steering box.Definitely a van column...You will need to collapse the one from the truck to work.The splines are the same and the column will go in the shaft from the truck.
