I would skip the Nissan ones myself. Expensive and weak. You can order a better stronger set form McMaster.com that will outlast the stock stuff and only costs like 50 bucks total. And when they do wear out in 5 or so years all you have to replace is the gas struts not the hardware. Here is what you need:
