I changed the gears in my rear end from i think a 2.43.. to a 3.73 now my speedometer is way off does any one know what two gears i should use in my transmission and on my cable to get my speedometer to work right .. is there a chart that i can use to calibrate it.. ??? please let me know.
thanks everyone.

You'll need your tire diameter for this one, you can get it from the TCI site mentioned above.
