A compatibility nightmare
Here you see the four types of non-rotation washers that Shimano makes for these hubs. Our small-parts kit had the 6 (white and silver) and the 8 (green and blue). We tried to install the hub with these. God knows we tried. If we used the 8s, then the cable guide (into which the shifter cable housing inserts) would be oriented too high, such that the cable would get tangled in the top loop of the chain. If we used the 6s, then the guide would be oriented too low, such that the guide itself would rub against the bottom loop of the chain. After much swearing and fiddling, we decided that we needed one of the other types of washers, neither of which came in the small-parts kit. (Shimano's logic here baffles me.)
So back to Box Dog, where they very fortunately have a box containing, inter alia several pairs of each type. Quoth Emily: "Just take whatever you might need and bring back what you don't use; we have plenty." After reading the instruction manual and estimating the angle between the dropout opening and the chainstays to be more than 20 degrees, we went with the 7s (grey and black). Worked first try.
