Ian,
I do not think there is much in the way of parts at the lower end of the head stem. Just the two parts of the ball race (and the balls of course!) and a sheet metal dust shield. Or at least that is all the parts list suggests there is. The frame for my EW basket case is a little inaccessible, but I will see if a I cannot get a closer look at it.
