Torsion bar removal Blues. What happened here????

Picture 1... What's the Unistrut for ?

The I only had long u-bolts so the top is resting on the t-bar and the unistrut is taking up the void under the bar. What you can't see is that there is also a smaller piece of unistrut with the U or open end against the bar. Here's a pic.
