Yeah I know, but the moment I add a small blue fairing the shape of other two fairing changes to adjust and stick to it.
There is one chance by increasing the other two fairing width but in that too the difference between them should be minimum 2 m to make it non adjustable. Which is not possible cause the diameter of the tank itself is 2m.
It might have been possible to use tanks but in that case it would need to a flat texture, cause in normal or flat smooth texture it would look odd.
