Hi
I have several early pattern steering boxes where there are two tapped holes for item 8, spaced about half an inch apart. Only one is used. I had always assumed this was some sort of vernier arrangement, so that the column could effectively be turned by half a slot and then reclamped. This would allow finer adjustment, after which 6 and 7 can be tightened to take the strain off item 8.
