help need suburban frame specs

[bassmannh]

I bought a suburban that was in a slight wreck or so I thought, the back shackles on the front springs were bent towards the drivers side when it got hit in the right front fender,and lower front of right door, got hit hard enough to bend the shackles toward the left side about 3/4" when I removed the bent shackles the springs wont move back to the corect position under the frame bushing, I /forums/images/graemlins/confused.gif need the a measured diagram like the frame shop would use so I can see where the frame is tweaked, HELP PLEASE
