Here's a link to a post in this forum talking about getting the haziness off the lights.
http://www.contour.org/ubbthreads/showflat.php?Cat=&Board=aesthetics&Number=346679&page=2&view=collapsed&sb=5&o=7&fpart=1 FYI its best to use the search function before you post a question as often you can find the answer that way and not get pounced on by the "search nazis"
That conversion you're talking about I assume is the Mondeo and although I have seen one or 2 contours with it done they aren't a direct fit and it costs a lot to get them in.
If you have to replace your lights try a pick a part junkyard or you can call Bill Jenkins at 702-303-5379 this guy is really helpful to the contour people around here with acquiring parts for a good price.
