Hi Colin
I think the shaft is peened over the aluminium ball.
I have replaced the old ball on my Special with a modern aluminium ball that came with an M8 females thread. By grinding the shaft to approximately 8mm I was able to use an 8 mm dye to thread it. Perhaps not for the purist but it worked for me.
