>>6773106I pulled the neck part out of my Alice and shoved it into the head of my Miku, it works! But Miku's face is really sticky on the inside and a little wide on top due to age and a bit of warping so it doesn't fit well in Alice's head oddly. You just need to take the neck out of a new head to put it in the old heads to make new faces work, which kinda sucks if you still want to use the new head
