Mount the shock at the top and just leave the bottom end hanging loose. Loosen that big nut as much as you can, leaving a thread visible. This is to relieve a bit of the tension on the spring. Then take a long screwdriver or pry bar, place through both holes, where it mounts to the control arm, and twist until it lines up. Thats actually normal.. Then as far as the through bolt going through the shock bracket AND feeding through the bushing, use your jack to raise the arm until 1 side lines up.. insert the bolt and tap on it to get it about 1" along the way.. use your jack to adjust until the other side lines up and tap the bolt on through.
When your' done with all that, then tighten up the topside nut until fully seated, and then the 3 nuts holding the assembly to the wheel well.
