Shackle bushing

Use a pry bar to help put the shackle in the proper position while it is unsprung, then lower the car and as the spring lengthens under load, it should go back to "normal" position.
that happened to me once...

I tryed that did not put to much effort into it tho,its all apart now,just waiting for shackle bushing,leaf spring,should be here Monday :D
