Motive GM10.5-488X ring and pinion gear set for GM 10.5 inch 14 bolt differential. The box was damaged in shipping, and the pinion gear has some slight damage to the edges of 3 of the teeth, and the threads were also slightly damaged but i do believe it can be fixed by filing/ smoothing out the teeth edges and rethreading the threads using a nut or dye tool. I'm not sure if this gear set is new or used, appears new but can't say for sure Please see the pics
