Easiest method and always works for me:
Park on level floor, put your weight in the seat, set your ride height, air pressures, what ever else.......
Adjust the drivers side ladder bar so the front heim bolt will slip in and out.
Now pull the bolt and adjust so that the heim is 1/2 bolt hole below the hole. Jack the bar up and insert the bolt.
You are now close enough to go to the track and test.
