I'm not quite sure,
They say it's available for "all" vehicles, and since yours was made with the round American headlights, I'm guessing it should work. If you ask them, they might know.
As far as converting to Euro headlights, I'm the only person I know of that opposes the idea. That's a good question to ask. Personally, I like the big, round American headlights. It makes the car look a little more old-fashioned, but in a good way. I think the Euro lights are good because of the better lighting they give, but I think they don't look too good on the 240 and 300D's. I don't know, it just doesn't look "natural" for some reason.
