You can still get them new from Nissan. There were two different styles, those with pre-tensioners and those without. The pre-tensioners work with the air bag system and during an accident when the air bags deploy, will lock the belt in place. You can go to NissanPartsDeal.com and look up the part numbers for your vehicle. When you click on the part number, it will bring you to a page that will give fitment info, like the production dates that part fits and, if you searched using your VIN #, if it will work in your specific vehicle.
