If it's a manual, then it definitely is not a North American Spec (NAS). Only automatics were officially delivered to the US and Canada. As far as I know there is no difference between UK and "the rest of the world" spec. apart from the steering wheel being on the right or left hand side depending on the destination market of course.
So you should be good by shopping for "rest of the world" spec parts I think.
