The euro bumpers had the foglight mounts built in to the bumper itself, whereas the north american grills have the mounts for the foglights. When I installed my euro lower grill I took my stock grill, hacksawed the fog mounts off, drilled a couple small holes (only visible from the rear) in the fog mounts and the euro grill, then used black zip-ties to hold them together.

Actually I followed jwardell's guide: http://www.jwardell.com/focus/grills.html

His guide shows using zip-ties in the middle of the grill too, but mine stayed in place fine just being secured at the ends. It'll turn your stock lower grill into garbage, but they really arent worth anything without the foglights anyway.
