Why won't they fit?
If the seller is being honest, they were ordered for a Contour racing team, not a Mondeo, so one would have to assume that if they were ordered for use in a Contour, that they should fit a Contour; but that's just my thought on the matter.
They look sharp too. Now if you could only get glass lenses that used the latest bulb technology, for the best of both worlds...
