No, not really. Dusters produced in 73 and 74 in many ways are better than the early cars. They have factory Electronic Ignition, Better Front Suspension with larger spindles and big bolt pattern wheels, Real Seat Belts, and a safety beam inside the front doors. The 74 360 Duster was best Duster, and as powerful as the early 340's. It came with a 850 cfm Thermoquad, front Sway Bar, Disc Brakes etc.
