The missing image of the bare body is shown further down in the thread.
I reused the original worms and had Joe Foerhkolb drill them out for me. His equipment is a bit more accurate than mine. They are a slight friction fit and held fast with Loctite. After I got them back I needed to drop the worm down the shaft a bit. This was accomplished by applying some heat to loosen the Loctite. Once it cooled it held fast.
