New spring install?

Ok, here's an update. As you can see in the first photo (above), the shackles were almost horizontal. I hooked a come-along to the shackles and hooked it to one of the tow rings, on the front of my truck. I had the rear end hanging. Now the shackles are almost perpendicular. But I can't pull them any further because it starts to pull the whole rig.
Also, what would the ride be like with the shackles the way they are?
Any ideas?
Thanks
