Hey Roy! To mount 25-1/4" long springs like item # e57SR, you will want to space the Tandem-Axle Trailer Hanger Kit item # APT8 29" - 30" apart. With the equalizer being 7-3/4" and the shackle straps measuring 2-5/8" you'll definitely want to mock this up on the ground before installing it.
I have linked a faq below that has quite a few specific details about setting up a tandem axle suspension system and what to look out for. I recommend taking a look at. If you have any additional questions feel free to reach out in the comment box below.
