I've just acquired Aragon, the modern version of the car-type powerdasher (repaint of Siege Cog), and it has two right arms.

How might I get this fixed? Is there someone out there with two left arms? This wasn't bought from a retailer, so I won't be able to return it that way (not that that would get me a fixed Aragon anyway - who would have replacement stock 3 years later...).

Thanks.
