The part they sent you, 37300-EA500, is for an LE, which is the only model that has the auto transfer case, which is larger than the non-AWD transfer case. Perhaps by "STD" they were referring to the transfer case rather than the transmission? I would return the shaft and use the 37300-EA510, which is listed for the 05-07 Pathfinder S, SE, and SE-OR models. There are no standard transmission R51's available in North America. FWI: Nissan #37300-EA510 has been superceded to part number: 37300-ZL91A.
