Oh, I was under the impression this was a horizontal difference not a vertical difference.
Search "Ranger lean", basically because the battery (some later rangers), driver, and gas tank and some other extra parts are all on the driver side they tend to wear out the driver side springs just a little bit faster. Some do it worse than others. So the drivers side has been known to sit low at times.
I also thought you were talking about the coil bucket on the frame. There will be a set of teeth on them that kinda grip the top of the spring. I'm really sure there's a pocket for the end of the spring. At any rate, the spring will twist in only one way (following the helix of the spring), and once it hits the edge of the bucket by the frame, it's in and where it's supposed to be.
Apart from all that, the only thing left is removing/adding a spacer under the spring.
