Aluminium saddle clamp for a Cervelo S2

Hi, I got a great deal on an S2 but having a saddle issue. Have tried my national agent for Cervelo but no joy. So wondering if anyone on here would know about where I might get an aluminium saddle clamp ?

No, thats the seatpost. This is for the saddle, the carbon rails are thicker than the ali rails. Thanks anyway
