Hello John
If you look at the previous post in this thread from Dennis Nicholas, he explains how the lower thrust washer BM42 is peened onto the worm gear at the bottom of the column. The six segments allow fixing at 6 places. From memory there is another brass (?) washer in the steering box onto which BM42 bears. I wouldn't expect this washer to rotate, but don't know if or how it is fixed to the casing.
Due to the worm design, the thrust is taken on either the upper or lower worm thrust washer depending on whether you are steering left or right.
If your steering box is badly worn, unless you have a well equipped workshop it may be cheaper to source a usable secondhand replacement box rather than spend money with an engineering shop to fabricate parts. Only you can decide.
