Welcome to the board, Dudesparx!
At one time, long, long ago, a body kit did exist for the Mark. On very rare occasions, you'll see one, or parts of one come up for sale here.
Here's a post for one that came up relatively recently. Sold, of course, but at least you'd know what you are getting into.

Another option to change the look of your ride may be to keep an eye on our vendor "Mark VIII Muscle." He's currently working on a replacement front bumper for the second generation Mark, and I believe he has been encouraged to produce one for the 1st gen, if all goes well.
