I have very recently (two weeks ago) changed sprocket and chain, at the same time I ordered the modified nut / washer quoting the part number gained from this site - This was ordered thru my local bike spares dealer (CMS in Exeter) and they supplied under the modified part number 90891-10124 (genuine number on the bag) so it is DEFINITELY available and a current part. - CMS do mail order so give them a call and I am sure they will sort you out, as I recall they had them in stock, think it cost me @£9.
Hope this helps
