Help!!!!

I recently bought a Lexus steering wheel off of ebay that was supposed to be for a '01 - '02 ES300. Now I know that it could not be off of an '02 because they went from four arms to three arms. But, when I got the wheel and took it to the dealer they said that it was not from an ES300 because it ws too big. Later, I called the dealer's parts department and they said that there should be a 10 digit # followed by to letters and that they could only tell me what wheel came with my '98(big help). Anyhow, does anybody know where this might be, I have looked all over this thing and I dont think I missed it, but sometimes I am not that bright.

I have attached a picture if it will help.
Any help or ideas would be appreciated.

thanks
