The wings are structurally different. The attach bolts are two bolts sizes larger, there is a steel strap on the spar to absorb the firing loads from the external hard points, the pitot tube is mounted much further outboard on the left wing to make room for the hard points, i.e., different part numbers which would make a major alteration
