sence i own 97 i know i need a new drive gear to correct speedometer i will be running 35's with a 4.56 gears in the axles i know 4.10 gear would put me back to stock so i gonna need a lower tooth count like a 19 tooth???? they got 23, 20,19 on summit site dont say anything else

 

found part of my question



driven gear teeth - drive gear teeth x axle ratio x tire rev a mile/1000 - stock drive gear teeth x stock axle ration x stock tire size/1000 = new drive gear tooth




next question is what is the stock drive tooth size for 3.55 gears????
