Are you talking about the 96 Sidekick in your name? if so, the gear that he would be refering to is on the end of the cable where it goes into your transfer case, there is no gear in your instrument cluster, that end of the cable has a flat on it that goes into the back of the speedo gauge. If you get under your ride and look where the rear driveshaft comes out, there will be a cable going in right near there (directly under the 4x4 shifter), it will take one (i believe 10mm) bolt and the assembly will slide out.... (be prepared as you will lose some gear oil) there will be a white plastic gear on the end of the cable. You may or may not be able to find one, I have a few of em still on old bone geos at my place, but you should be able to get a replacement at a local U-PULL-IT for a few $$ with only basic hand tools.
