I have been doing some restringing on these CTVT bodies for a friend, using the method shown by dr_cyclops, in this thread.
It's been a lot of fun, fixing these. All of the bodies shown have been done this way, except for the one on the far right with the white hands.

It had the oval opening at the top of the pelvis, as I mentioned (Some are round, some are oval).
So, I used my Dremel to round it out a little in the center of the opening.
After that, I was going to use the heavy elastic cord, but I decided to give the original rubber bands one more try.
With the bands twisted. the figure still had a problem, so I tried with the bands installed straight up and down, and I found that it was standing upright as well as the others,
so that's how I left it.
