I'm sorry I searched and could'nt find anything on useing the whole married setup out of a tracker and then putting my sami case with low gears behind it. I'm thinking of swapping to toy axles and will lose my 5.12 diff gears. I have 5.14 low range gears and with dual cases I think I could have good gearing for 35" tires with stock toy diff gears. Has any body done this yet? I will likely have to extend my wheelbase for driveshaft angle but a little longer would be good anyway. Any input would be killer thanks!!
