I had those pieces left over too! I replaced every part, old-for-new, but ended up with those little spring things extra. My brakes work great, waaaay better than before the rebuild, so I must have not needed them. Maybe for a different year or RPO?

As for the wavy washers, at least on mine they were not obviously wavy. There was only a very slight bend in them, you really had to look close.
