Previously, there used to be an email alias called partshelpindia at fiapl dot com. In the past, there used to be quick response to emails sent to this alias for issues related to unavailability of parts. May be you can try mailing to this alias, if it bounces, try @fiat.com, of course, with copy to mangesh. By seeing your name in the email itself they should be able to recognize you. Also, consider quoting all your threads in the email signature, for all forums.
