ok this is how the process works. they made the first prototype. they fit it. they make changes. they make a second prototype. they fit it. they make changes. they make a third prototype. they fit it. they make the final product. we are only 2/3rds the way through the development. when they are dont they will be perfect. the paint may be a little off, there may be minor changes, it is part of creating a product.
