I don;t know if its any help but heres a few pictures of the LCS steering box i saw today.
Sorry if they are to big (i'm not sure how to resize

)
I have more pictures but its difficult to see from these, I think it looks the same as the drawing on page 5 of this thread, apart from the way in which it mounts to the chassis rail. I'm sure i read it here that it may have been modified (in what way

),
"Modified" Adapted? ? ?
If the mount on this LCS Truck were to be Cut off at the point of it's bend and a plate welded on or straightened out instead of bolting through the top and side of the chassis rail it would look like the drawing.

Edit... the pictures above seen to have lost the right hand side, Resize
Edit 2... the pictures above have now be resized . But alas, although seem to be similar/or have parts that look the same, looking at the drawing again there not.
No banana for me today

and I thought I was being helpful
