To pick out the correct suspension components for a trailer you want to do it by most importantly picking out the springs that closely match the capacity of the axle capacity needed. That is priority one.

For example if you were using the springs part # 1020, # e66SR, # e34SR, # e28SR, or # e57SR with the hanger kit part # APT5 that comes with equalizers that are 7-3/4 inches long you would want the hanger spacing to be 29-1/2 inches which is pretty close to what you have. All of these springs are 25-1/4 inches long.
