If we go with that route then ady must add the face plate on vader's head.
Are you referring to the right side of Vader's face mask? If so, this doesn't need to be added as it wouldn't be visible in the scene (part of the meditation chamber is blocking the front of Vader's head). Only the raised crown-like section is visibly missing (assuming the mask is on).
ESB's helmet was meant to be 2 pieces i think
Doesn't that just support what I said?
