Chris, the dipped curve in the bumper that clears the grille is a little different on both cars... I don't think it would be hard to fix though, you could just modify the grille instead of the bumper if the lights end up fitting well.
We are going to put my SVT bumper on Jeff's Mystique to check that out very soon. I'll take pictures as we do it to outline what needs to be done to make it fit. If only the weather was milder up here!! Brrr...
