I hope this will be my last assembly question

Now I have all head mechanics and linkages installed and properly aligned. However there is a small problem: the swashplate to hiller rod gets in contact with the seesaw (red circle on the picture below).
Turning the washout unit clockwise (in relation to the rotor head) will fix the problem but it's not an option because I am pretty sure that the current alignment of the rotor head relative to the washout unit is correct. Given that, I think I have only two options left: to put longer pivot ball on the hiller (green circle on the picture) or take ~2mm from the seesaw at the point where it gets into contact with the rod (red circle).
Please advise me what option to choose. How would longer pivot ball effect flying characteristics?

Thanks in advance,
Slavik
