    Dave,

    Calculate Speedometer Gears

    The Hudson Speedometer will work as long as the cable housing will screw onto the back. I used a GM Cable & Housing with my Turbo 350 Trans. The Odometer is accurate using a 2.87 Gear Ratio. (I did need to 'alter' the speedometer end of the housing to screw onto the Hudson Speedometer)



    To get
    acurate MPH using your rear End Ratio & Tire Size
    I have used a Formula by driving between two highway mile marker then calculate the measured mile vs the odometer reading.



    However to simply further just go to the TCI Web Site and use their free automated Calculator by Typing TCI - TECHNICAL INFORMATION Speedometer Gears in your Search window.



    Then enter yout vehicle gear Ratio & Tire size. You can buy the gear you need right from TCI..
