I found this site when I was looking for N9 batteries last year....
KLC Finland
You might find their YouTube helpful too.

Unfortunately their English version of the site seems to not get updated much if at all, it still hasn't shown n9 parts, but in the Finnish version of the site they have some N9 parts, if you scroll to the bottom of the page I linked. They're a bit expensive for some of the parts e.g. 79.00 € for a body assembly, but if you're prepared to pay a premium to know it's genuine you might like those guys.
