Sorry...I think I would try and just build it without a head for now. Maybe Yamato will eventually release a new kit with more then one head (like the new strike with the 1S, 1A head options) if so then you could scavange a head. Maybe also post in wanted...maybe someone else will break a kit or sell a completed model cheap you could scavange the part from. Obviousley this doesn't help you now..but it's all I can think of.
