    Default Speedo Tooth Gear

    Ok, here we go.
    Tires = 33x12.50x15
    Gears= 4.56
    Trans= Auto
    Year = 06 TJ (X)

    I have been looking all over for the right speedo to use. Charts and forums all say 36 thru 40.

    anybody have the set up I do? Or know what speedo works for my settings.
    Thanks

    Just so you know...I found out the other day that a Hummer speedo gear fits the Dana 300. Haven't buttoned everything up yet to test the difference but will post up next week with results.
    81 CJ7, 30 over 258, did the Weber thing now I'm going with a Howell injection kit, 2.5 lift, SRS, and the all important M998 instrument panel with Equus gages. Also have a 71 AMC 360 to rebuild when I kill the 258.
