I’ve found two ways to do this, and I’ve used them in some of my previous MOCs. Sorry for not so good pics.
##Tall body
For bodies with two holes on the pelvis.
##1
Connect as you normally would for a tall toa metru
##2
Place the OX thing partially into the pelvis hole. Place the rubber band around it.
##3
Place a 4 long X peg with a stopper in the hole, trapping the rubber band in.
##4
Get the smallest ccbs shell and attach it to a chestplate. Make sure the point of the shell is facing up
Stretch the rubber band around the shell as shown in the picture.
##5
Tilt the chestplate into place and it will fit snugly.
##Short Body
For bodies with no holes in the pelvis
##1
Place a spacer in the gear hole
##2
Place a rubber band as shown in the picture
##3
Push the pelvis through all the way, and push “3” pegs into the torso
##4
Push a “3” peg with a stop through the torso and spacer
##5
Here I do the same thing in the first one, but with a different ccbs armor. You can put almost anything with the two pegs here.
##Adding Arms
This is a problom I’ve not fully solved. Try stuff and see what works. Here’s what I did.
##1
Start with these components, note that the eye pieces are on an XXO peg
##2
Attach the eye pieces and add the hands
##3
Flip
Add the OX pieces to the backs of the hands
##4
Attach the connectors
Let me know what you think, and credit me if you use these!
