Morris FAT C8 body types

[mudeng]

I enclose a couple of shots of the FAT steering gear.
The lower one is what I am interested in.
Does any one have a photo or details of how the steering column was fitted into the steering box itself.
The photo I took here only shows the lower part, and I would like a an idea of the back end.
At Duxford, scrabbling about on the floor getting this and other underside shots, I incurred the wrath of one of the "custodians", so was unable to get anything further.

A diagram from the manual would suffice, as long as I can get an idea of the shape of the steering box.

The upper photo is that fitted to the No 5 body, and is a totally different casting, (bless).

Thanks

George.
