1. A gear box assembly for a vehicle comprising an input shaft, the gear box assembly comprising:
a housing that defines an input gear indent, an output gear indent, and an idler-gear indent, wherein the input shaft is positioned at the input gear indent;
an input gear operably connectable to the input shaft;
an output shaft;
an output gear operably connectable to the output shaft, wherein the output shaft is positioned at the output gear indent; and
a removable adaptor selectively positionable in more than one position within the idler-gear indent;
an idler gear connectable to the removable adaptor, wherein the idler-gear connects the input gear to the output gear, wherein changing a position of the removable adaptor within the idler-gear indent changes a position of the idler gear relative to the input shaft and output shaft, thereby permitting use of input and output gears with different diameters or swapping the position of gears to alter a transmission ratio between the input shaft and the output shaft.
