In the lower left of pic related, the shield is mounted to her wrist using a black version of those spacers that are second from the left in your pic; the slightly large ones next to those are being used to mount the guns/shoulder pads to Zelnogrard in the far lower right of my pic.
The two sets of spacers you have without peg holes on them are just for lengthening her limbs a bit to make the transition between parts less awkward - note that your Yoko's left thigh looks a TINY bit larger than her stocking; if you detach her lower legs, put the two big spacers in, then put her legs back on, the transition will look a lot smoother. Same with her upper arms and the small spacers to the far left.
