Spring relocation kit installed wrong?

Last owner’s name happen to be
Mickey?
Not that im familiar with this sort of modification, its obvious it isnt right.
These sort of mods frustrate me.

Have seen some pretty effed up trucks where lifts were done so wrong.
Two with boogered frames i had to fix.
One with a 6” stack of flat plates and welded up u-bolts. I wouldnt touch that one.

Last owners name is not Mickey! But does happen to be one of my old nicknames

Thanks for all the info everyone, I’m going to try to find a local car and take some more measurements or maybe just buy the rear half of that yellow kit that locates the location to the original mounting points definitely seems like the most accurate way
