Hi coachcollins42
I may be able to help. I converted from Alko axles and the wider Alko equalizer to the Dexter smaller EZ flex. It was work, but I did get it to work. I have 5,200# axles tubes with 5,000# of springs. (2,500# each spring)
Tell us this:
What is the original center of axle to center of axle? as measured horizontal across
Does the spring pack sit on top of the axle tube or below the axle tube?
Can you tell us on the new springs, the vertical distance at the top center of the long leaf with the spring eyes, up to the centerline of the 2 spring eyes? I know on the old ones, they are flattened and you can't get a good number, but you have the new ones and I may be able to help some on the old ones. Take the dimension with no load on the springs
See some pics of mine. These pics are part of a lot of work I did replacing my axle tubes which had excessive toe out, hanger locations where not right creating heavy tire wear and reinforcing my very long spring hangers from bending. And later converting to 16" tires to go to LT tires in place of ST tires. So do not jump to a conclusion on what you see until you can confirm it from me. I have been through 4 different equalizers in this process...
Here is the EZ flex all together, original axle tubes, springs and spacing
No axles but you can see the springs and dexter shackles
Old axle
Old Alko rigid equalizer setup and some dimensions
The other side
Hanger distance. One of these hangers is all messed up.

Hope this helps
