well it might be cheaper in the long run too go with the 203 too 205 transfer cases. If a 203 will bolt right up too a 700r4 (IS THAT POSSIBLE WITHOUT ADAPTER)then he will only need the one adapter too go from 203 too 205 but with toyota stuff he will be out the 500 too 600 bucks for the adapter too go from auto too toyota case then another 450 too go too the 2nd case so eather way its gonna be about the same.
It all comes down too ur driveing style/what you want.
