The MKII Mondy lights compared to the Contour lights are different. From what people have looked at, the curve on our lights is slightly different then the curve on your lights (where they meet the fenders). It is also assumed that the Mondys take different grilles then the Contours do so I would assume that the lights are different there as well.
Unless you are in continental Europe, we drive on a different side of the road, which will give you a pattern that will blind oncoming traffic.
If you still wanted to try, look though our links page near the main page. I am sure you could find a vendor that would sell you some to let you try, as long as you paid the shipping to return them if they didn't. Excel Styling Products was going to do this for me with a set of MKI Morettes.
There is always custom work too!

Anything will fit that way.
BTW, I was guessing you have a MKII. The MKI Mondeo lamps and the pre-98 Contour lamps look an awful lot alike (but again there are differences).
