I know Keith on this board, I think his SN is SY2173 or something like that. There is a Sy/Ty mailing list, but that won't do any good.
Good luck with the Dak, my whole family owns them and we've never had any problems with them. In fact my dad has one just like yours, its a V6 auto with very bad paint. Still runs great though and never been in the shop.
