Carter 4640SA Date Code Question

Why is it wrong? Maybe not assembly line correct to a 69 car, but from what the OP posted. It was produced by Carter for a 69-71 car.

If it's a 69 car with a 71 carburetor? If the date code reads like Murray was talkin about. Also the SA suffix like HemiSSDart said. The SA is aftermarket, like the old Carter Competition carburetors.
