    I just had my 4.10s installed and now my speedo is off. I run 35's with 4.10's, does anyone know much it would be off and where can I get gears to correct it. /forums/images/graemlins/ears.gif

    Check the tranny shops around there. They usually have a box of 'em lying around...

    Dealership doesnt have the drive gears anymore, only the driven gears are available now. Checked today too.

    Your dealer is either lazy, an idiot, or GMpartsdirect.com is wrong.

    Driven gears for '85/86 K10/20 t-case (208 of course):

    14037996 18 tooth blue drive gear used for 2.73/3.08/3.42 axle ratio

    14037997 15 tooth gray drive gear used for 3.73/4.10 ratio
    Those are the only 208 gears listed for '85/86.

    '996 shows up for sure with GMPD, $12.36.

    While I'm here, the *only* speedo driven gear for the '85/86 205 is PN 6273992, red 7 tooth.
