With all your mods (top, smiley and headlights) I finally get the look your going for...a 997GT3, correct?
If that's the case, have you considered the front markers/turn signals in the bumper? I don't know how close the 987 or 997 bumper curvature (and lights for that matter) match the 986, but if it was the same (and since you have the ability to model plastic and have already cut into your bumper cover), there's your solution.
How exactly did you fabricate your covers...they don't look printed. Vac form? You don't have to tell if it's a proprietary secret....
