I just need a waist swivel added to Fall of Cybertron Shockwave. If you can figure out a way to make it an ab crunch/ab ball joint without wrecking the stability, that would be even cooler. Let me know if you're interested.
yup, interested... I can probably help you out with it... I've looked over pics of the toy and it appears doable. I do not currently have one on hand. Are you just needing help on doing it yourself? ie- do you just need a ball joint or joint options? Or you want the mod done?
