    Yes, that portion is the range box. I believe the nut size is 1 3/16" like zakk said.

    thats what i got my $ on is 1 5/16
    but it may even be a 1 1/8 ""
    also ya need the 1/2 " drive as the 3/4 drive scockets walls are to thick to fit in the yoke hole
    the large kit from 1 inch up to 1 1/2 " by 16ths is a great investment if ya can swing it
    as they are all commonly needed sizes for ball joints and 208 & 241 t case drain and fill plugs and yoke nuts for axles and t cases
