Started installing these gears today, they fit just fine - or at least they will fit just as soon as I can get my hands on a thin wall 1 5/8" socket to get the pinion nut off with. Already got the diff and the housing cleaned up and reassembled with the new ring gear. The chunk is unbelievably heavy and is almost unmanagable when its fully assembled. I bet it weighs 175lbs.
