A class 7 bolt of the same size and thickness will suffice. There’s no need to pay the exorbitant prices of the dealership. I remmeber having to purchase a nut and bolt for the front knuckle where the strut bolts onto it an paying over $13 for the set.
Save some money and put in a non dealership recomended part.
Can’t the guy at the parts counter at Nissan tell you the part number? Everytime I need any bolt or bushing or little piece of plastic the guy finds it for me with his eleventy billion diagrams.
