Early on they did make a left side tow hook available on the 2nd gen. Not sure why that stopped. The holes are still on the left side because the frame is also used for the non North American version of the Frontier. It's sold under the name Navara. The right hand drive versions get the single tow hook on the left side.To the best of my knowledge Nissan never made a hook for the driver's side? They did however already thread the frame on the driver's side to accept a factory tow hook.
