You have to get all angles in the steering to be 90 degrees. So you have to adjust the lenght of the turnbuckles in a way that you get 90 degrees everywhere. After that you should put up the horn on the servo. And if it still needs a trim it's only 1 or 2 clicks.
With this 90 degree angles the angles of the servohorn is the least important, but the other ones are.
