Hey Craig, to measure a leaf spring to pick out a replacement involves measuring from one spring eye center to the other without any weight on the spring and then picking out a replacement that is just a little shorter than that as they tend to flatten out over time. Usually between 1/8 to 1/4 inch is about right. Also you will need to know what axle capacity your trailer has as well.
For example, the part # e22YR is 26 inches long and is for a 4,000 lb rated axle.

Hey Craig, how did your measurements turn out when checking the length between the spring eyes? Once you had that and the axle rating, were you able to find a leaf spring that matched up well? Your update could make it easier for others doing the same replacement.
