Fits 1968 V8, 49.5" long. Less rotating weight means more horsepower to the rear wheels which makes an aluminum driveline a must for any performance oriented Mustang. Have a street car? You'll love the smoothness that comes from the lighter weight and lower vibration of an aluminum driveline. Our aluminum drivelines are complete, including a new front yoke, tube, and u-joints, all installed and balanced as a complete unit, ready to slip into your car in as little as ten minutes. Ships UPS oversize.
