    For my 208 it was the orange gear for 3.73 w/ 31s and the green gear for 3.73 w/ 33s. Depends what tire size you are running. I'm not sure if the gears are different for the different cases or not, but if you want the number for the green gear I have, I can dig it out for you.

    Spedo gears are color coded.
    Here's a handy site with most all the info you need: <a target="_blank" href=http://www.tciauto.com/tech_info/speedo_gears.htm> TCI spedo Gear Info</a>

    If I understand this chart correctly, the DRIVE gear is the one inside the tcase on the shaft while the DRIVEN gear is the one in the end of the speedo cable that connects into the tcase. Is this correct? I have a 208/700 combo.
