Ok, I swapped out my bad diff (3.27 non locking) with a 3.73 trac-loc. Car is running perfectly now, except for the speedometer (of course). This car has the digital dash board. How do I adust the speedometer? Does it still use a speedometer gear, or is the digital dash board input different? If it is a gear, does anyone have a calculator or chart to point me in the right direction for the correct part?
Thanks
