Does anyone know what the correct color or tooth count is for a speedometer gear that would have been used with the 3.08 rear axle? I had a yellow one in there initially, and that was 10 MPH off (low) at 55. I don't know how many teeth it had... I think 18. I then went to a white one which was a 17 tooth gear. That one is 8 MPH off at 55. My dealer has indicated they don't think any other colors are available. If anybody actually has a 3.08 gear from a truck equipped with same, I'd love to aqcuire it. I'll also mention I'll probably need 2 of them, as I am looking for another 3.08 axle to install at this time as well.
