Poor suspension

So... I have new upper and lower ball joints. The Car was completely dismantled K frame included and re-bushed. It got a real good rebuild. New Shocks. Converted to Disk Brakes. Torsion bars are original????? If that is a consensus I have no problem upgrading them. I just think its odd that this happens on both sides. I don't recall seeing the K frame broken or this happening when I bought the car but it literally went from the trailer and I drove it into the shop so I don't really have a pre-condition. Does anyone know if the torsion bars need pre-loaded when installing them. If I recall, when I took them out they pretty much slid out with the wheel hanging down.
