Help needed with a part No.

Hi All,

Have been lucky to get hold of a new AMG rear bumper for my 2003 s211 E270cdi. It has three part no. stamped on the back!!!

A 211 885 10 25
A 211 885 14 25
A 211 885 11 25

I want to use it as a E55/63 rear bumper, with the cut-out's for quad exhausts. In the pics I have seen of the E63's it looks like the rear bumper also has a rear diffuser/black lower trim. Can anyone confirm what this part is please.

Please can anyone show me a parts drawing which shows other bits I need to order, as I have just the 'bare' bumper shell.

Regards
