fasteners. These are Auveco 17472 or you can get from Nissan. The upper center retainer holds the top lip of the fascia to the upper reinforcement with around 7 10mm bolts (you can see this if you remove the center panel). The lower retainer uses 3 nuts to attach the front splash shield to the fascia. The left and right front fender shields (L-shaped) are held in by plastic fasteners and some screws and nut clips. Hope this helps.
