Gentlemen, I am almost ready to execute the mission, rebuilding the rear suspension. I have a new set of ESPO +2" springs, proper U-bolts, CALTRACS, rear-hangar bushings, and new proper length shocks for the increased ride height. My front spring eye bolts and nuts look very good, no corrosion so I intend to re-use. Shackle bolts look pretty decent also. Before I start wrenching and disable my car, I want to make sure I have everything I will need. Here's my concerns: 1) My rear end is not quite centered, its about 1/2" closer on the left side and my tires are big enough this causes rub issues. Is it a realistic expectation that I can center it up when doing this spring replacement? Can I move it over 1/4" without cutting off and moving spring perches or centering tabs? 2) I was thinking of using locking nuts to replace the shackle nuts. What thread size are they, everything I have found says 1/2" but no thread info. I would just take a nut off but Im anticipating destroying it in the process, and I'm still driving the car. 3) Am i forgetting any parts or hardware that I will likely need to do this job? Thanks for the help from those that have been there, done that.
