    I was looking at TCI transmissions web page to find out what speedometer gear I need to make my speedo read correctly, but its greek to me. It asks about the number of teeth on the drive gear. I assume this means the gear the speedometer gear meshes with. Does anybody know what this number is off hand. Heres my setup 350/7004r/208 with 3.42 and 33's. Thanks for the help

    mine was 18 teeth...just change the driven gear the other day

    go by the actual measurement of your tires, not the rated size

    my "33"'s are only 31 3/4" tall /forums/images/graemlins/shocked.gif
