The larger hood pad will fit your model.
Good news for you...

Some places where you can get the pad.
Could try the above store (i.e. Fast lane), but I do not know if they will deliver to UK.

There is one particular place where I get most of my parts because they are the cheapest. Their name is the Benz Bin. Their phone is 888-628-3247 or fax them at 609-392-9922. They will ship to the UK. You don't need the part number. You can talk to the guy over the phone. He will give you the part number. Be sure to order OEM equipment. It does make a difference.

Good luck!!!
