Speedometer Calibration. What gear?
Guys. I am looking to see if anyone can help me find the right speedo gears I need to have my speedo read correctly. I am tired of it reading 30-40mph fast. 
I found that, but the problem is I am running 4:10's. You guys out there running this gearing what speedo gear combination are you using?
Thanks!!
For 3.42/3.45 rear ends, you need a 7 tooth drive gear and a 19 tooth driven gear to make the speedo accurate.
For 3.70/3.73 rear ends, you need a 7 tooth drive gear and a 21 tooth driven gear.
For 3.08 rear ends, you need a 9 tooth drive gear and a 23 tooth driven gear.
For 3.70/3.73 rear ends, you need a 7 tooth drive gear and a 21 tooth driven gear.
For 3.08 rear ends, you need a 9 tooth drive gear and a 23 tooth driven gear.
Thanks!!
