I just wanted to let you know that the gt500 stuff is listed on eBay if you want to check it out.As far as it bolting up to a 13 gt not directly.I had to modify my bumper support that bolts up between the headlights.But you can buy one for a gt500 pretty cheap.Other than that it bolts right on.Let me know if you have anymore questions.Just one more thing no shipping.Thanks
