Realistically it probably doesn't make a difference. I like to have them in because it means the LCA torsion bar socket is going to be located exactly like it will be when the car is on the road. But it's pretty unlikely the torsion bar will move it much, because they won't slide in if they do.
Either way the motion of the LCA is going to be slightly different because of how it rotates without the adjusters in place. Dropping the adjusters is certainly easier than pulling the bars if the bars are already installed.
