You almost always need more than just the freehub body to make this HG conversion!
All of the axle components on the driveside end of the axle, plus the sealing ring that fits/presses inside of the threaded snout on the HG body, are needed as a complete set to assure assembled "stack height" correctness and proper sealing.
Get all of the parts together, from another hub, and keep them together! Do not attempt to remove the sealing flanged ring inside of the freehub body/bodies, as they are difficult to set in straight and easy to damage!
But note that there are several different standards for the mating of a Shimano freehub body to the hubshell. These all seem to have identical splines, but the stacked height (thus distance from spokes) can be very different, which (just as before, with the axle) can also cause insurmountable sealing and operating-clearance issues!
You have been warned!
