Right, it's just the big washers I was confused about. I think the comment above belonging to the UCAs is correct (at least I hope because it's all done!).

The picture cut the words off in the middle of my post, but my problem was that when trying to install the reservoir bracket the little screw tab fell inside the hole and is currently inside the frame. I don't think I can get it back (unless I were crazy enough to slice open the frame). I'm not too worried about it though. The reservoir is mounted, but I don't think it's rattling or anything. I might call the dealer about getting an extra one if I can't find one at Lowes.
