I want to fix my speedometer to read the correct MPH. I'm running 35's and 4.10 gears. I have a stock NP208. what tooth count do I need, and where can I get one? I found a chart online but it was for jeeps, it read 34 teeth, is that correct? thanks

Look at the driven gear in the T-case. It is really easy to remove. Look up the color or count the teeth. Then use the ratios of stock gearing and tire diameter to your modified numbers to find out how many teeth you need now. It won't come out exact, just choose the closest one. This gear is probably available for your combination, but if not, then you have to look at the drive gear as well.

Many of the various gears are available at your local dealer. IIRC price was about $6.00.
