Logo 550sx v2 servos

Hi,

I’m building a Logo 550sx v2. I have followed the manual and fitted the ball links as instructed.
Im using align DS620 servos and it looks like the control rods are at a slight angle. The servo arms looks as if I need to remove the nuts that are behind the ball end.

Is this right?
