Does anybody know the part # for a 12 bolt U-joint like to get it at O'Reilys or Napa?

ls1speed inc told me to get a napa part number 447 u-joint when i ordered my rear, also told me napa could press my bearings on the axles with the backing plates. i havent been by napa yet but that number seems a bit short and i was wondering if it was correct or not lol. this is what they told me to get for the 1350 yolk thats going to be on mine.
