[CSX 4027]

To my knowledge Shelby stopped making Cobra's in 1966. If there are any titled as 67 or later it was probably due to them not being sold. The comp cars and S/C cars were all made in 1965. The street cars could have either had 2-4 or 1-4. But, not a sidewinder. The straight up no part number aluminum piece would be correct for a 427 street car.
