Question:

If you need me to send a picture let me know I also think Im supposed to take the measurements from the middle of each eye to eye measuring 23 in the width is under 2 in

The length of the slipper spring is from the center of the eye to the end of the slipper. See the attached diagram below. The width and the capacity are also necessary when choosing a replacement, leaf count isn't very important and can vary. The capacity will be based on your axle.

For example, if you have a 30" long slipper spring that is 1-3/4" wide and a 1,800 lb axle you could use the # e29SR. I have attached a link to all of our slipper springs along with a helpful article on slipper spring suspension for your reference.
