    For the life of me I cannot remember (nor find) the speedometer codes, stamped on the back of our speedo clusters, that designate the corresponding final drive (rear end) ratios they are made for. Can someone point me to a reference or relate them here? Thanks!

    so now - what would be good information is to know what the gear inside of the speedo is (# of teeth) - based on which W number is on the back of the speedo. so when you go to replace the gear (when the odo quits working ... but the speedo still does) you can just order it from OdometerGears.com without having to take the speedo apart in order to be able to order, and leave it open until the gear arrives. anybody know any of this info?

    I will bet they can tell you based on the code.

    when i inquired some time last year, they wanted to know how many teeth ... i tried to give them the code #, and no such luck. maybe they have learned since then.
