Do you have 2 sticks for your t-case the only way i know to make a 205 do that is to make 2 levers to control front and rear shafts but that is usually for using low range in 2 wheel drive unless you have an entirely different t-case then it's not a 205 there is a t-case that does do that without being modified and again as usual i can't remember which 1 it is or a really bad senario, it is a 205 and, it's broken
