Hey Dan,
To find the correct replacement leaf spring for your trailer you'll just need to measure one of your current springs for its length and check the axle for the capacity. To measure you'll first want to lift the trailer by the frame to take the weight off of the spring. Then you can measure from center to center of the eyelets or from center of the eyelet to end of the top leaf if you have slipper springs. That measurement along with the capacity of the axle will tell you what spring you need for a replacement/spare.
If you need help finding it then just let me know your axle capacity and length and I'd be happy to look it up for you.
