Speedometer Gear for MPH Correction

I'm being told there is a speedometer gear from a Disco I that will come very close to fixing my speedometer. I'm running 255/85 tires with 4.11 gears. Did a search and couldn't find anything, who knows which one I need?

Step 1, measure the speed error using a GPS. Step 2, figure out what gear is in there. Step 3, choose the closest match.
