How-To: Help with installing Torsion Bar Adjusters/Assembly

Long story short. We took the duster to a shop to be lowered,the mechanic ended up stripping the block and bolt on the Torsion Bar Assembly/Adjusters.
We ordered a new pair.(both sides)
A couple of guys here on FABO told us it shouldn't be too difficult to replace and adjust them at home.

The new set. (Below)

Only problem is, We don't know how to install them.
We'd like some help please.

The car is a 1974 Plymouth Duster. This is how low it ended up.disgust
