David,
Actually it was me, Larry Johnson, who worked it out with a pencil. ... bow,
applause, bow, grin :-)

Another way to reverse the CV joint wear without changing shafts is to remove
and remount the CV joint backwards so that the grooved side is on the 'wrong'
side. As far as I can see, the CV joint is symmetrical and will do no harm
mounted this way. However I have not yet done this myself so I can't say for
sure if it would work.
