I remember a thread a good while ago about how to make the grooves for the o-rings and what size o-ring to use. I can't find the thread. Does anyone know the particulars on how to do this? I have access to a machinist, but feel I must be able to tell him something to start.

I'm rebuilding a 78 case and the shafts push through easily with my fingers. They have always leaked. Solving that mess would be a great improvement.
