986 rear bumper question (specifically for the 'Mericans)

[koosh]

i was wondering if anyone knew if there was any difference between an American spec rear bumper and a European spec rear bumper on the 986 boxster, specifically the license plate tub area.

i have looked through various ebay adverts and at members cars and there doesnt seem to be much in the way of differences between the shape on the bumpers or the tub itself.

the reason i ask is i am getting a shorter license plate for my car (UK spec) and i would like to shorten it and if possible (and if i could get my hands on a set) fit the US spec bumper guards on either side of the tub.

i have come from the VW scene and import parts are a big thing and its something i would like to keep going with my boxster!

any help would be greatly appreciated!

thanks!
