Ok, I will correct you. Every Cobra had a bill of materials associated with its build. Cars within production groups had changes in specifications as better products came on line. But there is a Materials List for the S/C cars that did not vary, except in the case of specially-ordered cars. Hence the S/C cars were all built to the same specs, using the same parts, and varying only in color or, in very rare instances, special equipment (such as "quieter exhaust" if you can imagine that).
