That's it. Going back to lockup isn't too big of a deal. The hardest part was getting the cup plug to hold in the tapped oriface. I just expanded the plug with a hammer. :) I left the checkball out of the shaft. Feels like I have five gears now when it locks up.

BTW: You can keep both a lockup version and a non-lockup version pump lying around, and the only change to go from one to the other would be switching the pump and converter. I was going to do this so I ordered a pump from a GSCA supplier. But I found the the stator support was a USED unit and it was installed such that I couldn't remove it. So I just converted the non-lockup pump back to a lockup.
