i believe to make them fit you have to fab new mounts, get a new grill, and modify the quarter panels just to make them look decent. not a cheap venture by any means.
the contour and mondeo bumpers are not the same due to different crash requirements and as much as the headlights of the two cars look the same, they arent. they have slightly different shapes, dimensions, and mounting points.
funny you couldnt find anything in a search, i did.
