torsion bar system, i need help

i have never messed with torsion bars so some of thse questions may seem stupid. I bought a 75 dart that had a broken torsion bar when i got it. I picked up a set of torsion bars and have read thru some threads on here on how to change them. However the torsion bars arent how i pictured them in my head so if you could let me know what all the parts and pieces are, and if everything looks ok.

Here is the back side of the cross member, i know this is where the end of the torsion bar slides into. Ill admit this is where i though the tension adjusters and stuff were but by looking at it i realize that is not the case.


this is the drivers side up at the wheel, the drivers side is the side that is broken. the piece that is sticking up, is that part of the adjuster? This piece is a lot higher than on the passenger side.


This is the passenger side


then there is this bolt, what is it for?
