Looked under my car last night--DUH!--the springs aren't in backwards. The rolls on the end are different. Offset roll on the perch, and center roll on the back.
The difference in the outer bushing size threw me. One huge problem with fixing it through the computer is the loose bolts. Do the loose bolts create all the slop causing something that looks like a more lousy fit than it is?
I wouldn't think that the correct torque would take up the slack in such a stout bracket. But I try not to think a lot because it makes life more freindly. So some mojo might whip everything into shape.
Beating with a bfh doesn't correct the problem even if it aligns. The probem is that the leafs flop around in the mounts.
It needs some assbone supporting the spring, similar to what Jim posts.
