  • Depends on which gear ratio you went with and what speedo drive gear your transmission has but definitely fits the automatic for your year pretty easy to install aswell

    Identical to original.

    Great replacement part along with the clip for the installation. It took me longer to put the Stang on the lift, then to install the gear.

    21 Tooth Gear

    A must have when changing the rear end gears of your automatic Mustang. Corrects the Speedometer dead on. Quick, easy installation. Not all shops carry these items, so its best to be ahead of the game and make sure you have every parts you need.

    21 tooth speedometer gear

    I purchased one of American Muscles' 21 tooth speedometer gears for my 1997 mustang after i swapped differentials going from a 2.73 gear to a 3.27 gear. I wasn't sure which gear i would need to correct the speedometer, but their detailed explanation of what gear goes with which transmission and differential gear was the most helpful out of anywhere else i looked. I received the gear and it was in and working perfectly in ten minutes. I highly recommend this gear, it and American Muscle will save you allot of time and headaches.
