Default Different speedometer??

I am wondering if anyone out ther knows if ther is any companies to sell different size plastic gears for the seedometer on a NP241dhd transfer case, I have 4:10 gears and went to bigger tires to get a little higher gear ratio and im running right about what 3:73 gears are compared to with regular size tires, i have 255/85/16 tires and at 60mph im running about 8 mph faster than what speedometer shows, any ideas??
