Im posting for a friend. He has a 2004 4runner. Its 4x4. To engage the 4x4 you have to turn a dial (no manual shifter). That plastic knob broke. He went to the dealership to buy a new one, but they don't sell the dial separately. They said he'd have to buy the full assembly...Which was over $100. That's more than he wants to spend on a plastic knob. Does anyone have one? Shipping is to Santa Barbara CA, 93101. Thanks.
