Would have asked the GT guys but they wont know i have the 03 04 cobra bumper and im gona get the HID conversion kit put on soon. Before i ask the american muscle EXPERTS if it will work im hoping maybe kilgore or uncle meat might know, if the HID fog light conversion for the GT will work on the cobra fog lights? Peep this its pretty sweet. http://www.americanmuscle.com/hid.html
