Diagram of composite leaf spring
To measure the arch, place the spring on a flat surface with the arch up. Measure from the floor to the bottom of the spring ('H' in the diagram), and then subtract 3/4" from the total length.
For the Chrysler the overall length (eye to eye) is 53 7/8" and the pin to eye length is 20 1/2" ('L' in the diagram). For the Chevrolet, the overall length (eye to eye) is 54" and the pin to eye length is 25" ('L' in the diagram).
