We don't have a way to look up the length of your leaf springs as that's not something that a record was kept for. But I can say that nearly every 3,500 lb axle spring out there needs the 25-1/8 inch replacement like the part # e54SR so while I can't guarantee this is the correct size it has the best odds by far as being correct.

The clip that goes around 3 of the leaves of the 5-Leaf Spring part #e34SR that you referenced can go either in front of the axle or behind it. Either way would be perfectly fine. I attached an FAQ on trailer suspension for you to check out as well.
