Let's not make this out to be some big conspiracy theory here. As was stated above by others, this is quite common in kits, and it seems to happen a bit more in Goldberg kits for some reason. Jester, it's nothing to worry about and like I said it's common. In your case were you have a notched part like your leading and trailing edge pieces build them to the parts. Start building with the parts at the wing root rib and then start building out. If they don't match the plans don't panic. Simply keep building using the parts to align everything. As you build make sure your ribs stay parallel to each other and that they are square to the leading and trailing edge.

It will build just fine this way.
