I recently purchased a used cargo trailer and would like to do a spring over conversion. It looks like I should be able to purchase some new hardware, unbolt the springs, roll the axel out, bolt the springs, rotate the axel and reinstall it under the springs using the new hardware. It's a 4x6 Interstate trailer rated at 2k#. I've seen the hardware kits online. Seems simple enough. Is there anything I'm missing? Any tips anyone can provide? Thanks
