Suspension parts list. What's missing?

If you loosen the torsion bar all of the way, take off the nut that holds the lower arm, and remember to remove the clip at the back of the torsion bar, the whole assembly will slide back and then you can separate the bar from the lower arm. You need no special tools for this. You're tearing the whole thing down, anyway, you don't need to remove the bar first. You only need the tool if you are trying to leave everything else assembled.
