These 17x10" SVE anniversary wheels are the same bolt pattern as your 1980 Mustang, and will fit on the rear of your car. The 17x9 version of this wheel will fit the front of your 80, as long as you upgrade your front spindles and brakes to 1987-93 5.0 11" brakes. If you bolt them on without the spindle swap, the front wheels may hit your struts unless wheel spacers are used. Be careful about your tire size in the front. 17x9" wheels are a tight fit on four eye fox bodies because of their smaller wheel openings. Max tire size you'll want on the front is a 255/40/17. You may also need steering rack limiters to prevent the wheel from coming in contact with the front control arm.
