    The shift pattern is different for one. On the 205, the shift pattern from far front to rear is: 4low/neutral/2high/4high. The 203 is: lowlock/low/neutral/high/highlock. The 203 typically has a large round aluminum extention on the rear of the case where the rear drive shaft comes out. Also, if your vehicle doesn't have locking hubs (auto or manual) it is the 203. I'm sure there are other differences but can't remember 'em now. chow
