Starter Motor OEM Parts No? FD, 2007, K20 Motor, Auto

Hi everyone,

I'm trying to get my starter motor replaced on my 2007 FD Civic. Its a sports model, so it has K20 Motor (2.0 litres), and it is automatic transmission.

I've call up many parts supplies and honda dealers, trying to get its OEM part number, so that I can purchase the correct starter motor. But no one is willing to provide me with the part number.

So question:
1. Does any one know a way I could get the correct part number?
2 Or is anyone familiar with this model, and is able to tell me the correct starter motor to get?

Thank you!

Edit: I found the following starter from Ebay, is it correct? http://www.ebay.com/itm/NEW-STARTER-...3f92ae&vxp=mtr

NEW STARTER MOTOR ACURA TSX CSX HONDA ACCORD CIVIC ELEMENT 31200-RAA-A61 RAA5K

Or can some one please tell me the trim levels :DX, EX , Si are? So that I can use a web site like http://www.oemacuraparts.com/index.php?p=home.

Mine justs says "sports' on the back.

Cheers,
