Best guy to get a hold of (if you liked the Contour quad xenon look) is the guy that made those in the first place (from the Contour site). Milan Motorsports. He could surely give you some good pointers. His e-mail should be: milanf07@hotmail.com (unless he changed it). He calls himself "Quicksilver" on contour.org and he calls himself "Milan" here on this forum.
I could give you some pointers if you had a pre-'98 Contour like mine, but yours is the post-'98 so my approach is definitely different, although I WILL supply you a link to my work, so you can see what I did on my Contour:

Like I said, mine's different, but you may pick up some pointers??
