It should bolt up the same, but keep in mind the 2WD Frontier has a different fender than the 4WD Frontier. The Xterra is closest to the 4WD Frontier. But, keep in mind the Frontier fender has holes in it for the "over fender," as they call it...or, what most would call a "fender extension." The hoods are the same. The turn signals are the same, but, I believe the plastic, inner fender lining is different between the two. Also, I'm not sure how well that "rounded" Frontier wheel well in the front is going to look with that "square-ish" or "angled" wheel well shape in the rear, Xterra quarter-panel?
