My Volkbitsu hybrid girl kept losing her pelvis piece, no matter what kind of glue I used to hold it together... (I sawed the Obitsu pelvis piece in half to get the Obitsu pelvis piece to fit with the Volks legs.)
So this time I had to work on her torso to get the Volks butt to fit instead... It comes in two pieces and is held together with screws, but the differences in how the Volks body and Obitsu body are put together made it a challenge... basically, I had to remove about 1/4"-1/2" of plastic from the bottom of her waist to make the Volks butt fit with the Obitsu torso.
