Dave,
Do you not have the illustrated spares list? If not, why not! It shows a very good exploded view of the rear hub. And I think it is one of the illustrations not containing a mistake! The washers, shims, and bushes are visually different enough that with the illustration you should be set, without resorting to need dimensions of the various components to identify. But if you need dimensions, then someone is going to have to pull down a rear hub to oblige.
