Yes x_dekin, I had the head made that way and the neck is resin so it can be adjusted
based on what body people use. The thickness and hole size only took
minor adjustments to work on my body. And once you have the head on
with the armor, the size looks fine.
If you're having an issue with assembly, maybe ask someone for help
or have someone else do it for you if you're not comfortable making
any minor adjustments.
I know when it's all in pieces like that, it seems a little overwhelming.
Maybe Woodrob will offer his services for assembly if you send him the body,armor and head.
Doesn't hurt to ask.
