So, even with the correction of the bushings the axle still sits and inch or so back on one side? If you frame is straight, axle perches are correctly aligned, and you have verified that both leaf spring packs have the same dimensions between spring eyes and from spring eyes to centering pins, then I would take a close look at the front spring eye mounts that are riveted to your frame. Has one of these been bent back, removed and welded into place, or otherwise tampered with? Again, just a thought.
