I supposedly had a 3.5 rear end installed by a local shop that replaced the 2.79 in my 1967 8" rear end. However, after adjusting the driven speedometer from a 15 tooth to a 21 tooth to correct the speedometer, the new rear end seems to be closer to a 3.73 than a 3.5.
Is there an easy way to tell what the ratio of the rear end is by counting the number of drive shaft rotations per wheel rotations?
Thanks
