The F-104C has a smaller rudder and vertical stabilizer than the F-104J. The J model is similar to the G model, which includes the provisions to carry under fuselage AIM-9 launch rails and wing hard points to carry additional drop tanks. The F-104J did not have air to ground capibility, only air to air.
