ooh thats a lucky find.. i dont know for sure.. but i dont see why theyd be much different.. the exhaust hangers for the tips would use the same mounting points under the car between the 2 models.. the bodies are technically the same... you have a tape measure? just go measure the distance between them.. left edge of the left cutout to the left edge of the right cutout.. measure on both the gt bumper and the cobra.. half of the difference between the two is how much you'd have to adjust the each exhaust tip.
