Candy/Minipla Gokai-Oh Gokai Trailer Cannon Ver.

So, I was able to find all the parts of the Minipla Gokai-oh Cannon version at a local Japanese supermarket except for the Gokai Trailer (the yellow one). I'm looking to see if anyone has any extras they'd want to sell. I'm looking for the cannon version because of the cannonball parts and the inner door sticker.
