sorry i dont know the part number. im in NY so i was calling the few junk yards we have on a weekly basis. Took about a year of calling but i got it finally!
its basically the stock roof rack from an SE pathfinder 02,03, and 04
yes the bolt holes line up exactly. all i did was remove the front and rear stoppers (not sure technical name) on the track, slid out the old cross bars, then bolted the new rack with the old track still in place. hard to explain in words but if you want i could take pictures and show you. let me know
