They both share the same part number.The hubs were used for the mower deck hubs also but were not welded on both sides.
I should have said will the PK hubs fit on the JD shaft, the part where the bearings ride. not the spindle. Or will PK shafts and hubs fit the JD spindle.I believe the dandy spindles are longer, much like those on a 24XX. It might put the front higher then he wants if that's the case.
