Right, and if you ever peruse the early Camaro forums the standard advice for First Gen Camaros is not to use the factory alignment specs for their car, but rather use the Second Gen specs because of the bias versus radial difference (that's assuming the reader was upgrading to radial tires). I don't see why a Cobra would be any different. It would seem that alignment specs for one type of tire are probably not suitable for the other.
