Negative Camber Adjustment - 1990 Club Car DS

[Springbok]

I have a 1990 Club Car DS with a 4" Z-lift (which uses the stock front suspension assembly). I noticed that it has a slight negative camber on both front tires. I've seen and read about the bolt in the middle of the leaf spring that is supposed to correct camber and even it up between the two front wheels, but this doesn't seem to be the adjustment I'm needing from the diagrams I've seen. Is there an adjustment, or is the leaf spring just worn out and sagging? I have an extra front leaf spring from a 1987 cart that will work, but I just want to make sure I'm not doing this the hard way.
