Parts interchange between the older and newer Aisin hubs. The older hubs had raised ears to turn the center engagement knob, having ears that stick out a half inch further makes it a whole lot easier to turn the knob into 4 wheel drive! You can recognize the older Aisin hubs due to the fact that the Allen bolts go through the top cover to hold everything together instead of having recessed Allen bolts with small bolts to hold the top on.
