OK. Understood, bmorgil! You're right, of course. I'll try to make the tool work and get the seals in the right way. I did notice that one of the seal guides was a bit banged up on the bottom of the ID. Perhaps from someone trying to do what I suggested long ago? I smoothed it out a bit with the Dremel just to take any sharp edges off. Both guides are in decent shape, though and still tight.
