Right! I saw that little key the plastic washer needs to sit in. I'll double check it. I've already cracked one of them, so I'll probably order a couple from Rivendell. Looks like they sell them for $4.
I think I have a bit more filing to do do, to get the shifter stop to seat a little tighter to the frame.
