Spur gears huh, i have an xfactor and there was this guy on the XTM xfactor forum that made steel gears for the factor. i asked him about making some for my mt2 if i provided him the parts. he said that he could.

i believe this is his site www.1320.4t.com
his name is 8man i believe. like i said its been a while for me on the forums so i may be wrong. good luck with this
