so I bought this car last summer and didn’t have much time to enjoy it, either way mid way through the year I developed a new clunk, looking under the car I noticed my shackles were pancaked flat against the frame, upon further investigation this car has had a spring relocation kit installed, now this got me to thinking that it may have been installed wrong, I also noticed that the rear shackle hanger is offset from the frame which most installs I have seen are centered on the rear frame rails

Hopefully someone can chime in and shed some light to give me a direction to fixing this problem? I’ve attached a photo with a measurement off the original frame location for the spring hanger to where the Center of the hanger is now, approx 4 1/8” if someone can reference their car for me to see what went wrong on mine

looks like the springs are too long or the brackets are installed wrong
 
I just put the stock hanger up to get a measurement. The bracket attaches to the vertical surface, and it's 1.5" to the fixed pivot bolt.
 
New springs as well? Can you tell?
 
Are both sides the same way?

Drivers side is welded the same and is close to the frame but not touching as the passenger side is.

I am guessing the springs are used as the gentleman I bought the car from had a full parts car to swap the drivetrain over, said it was a 72 dart parts car but came with 727 trans and 8 3/4 diff where this yellow car was originally /6 auto and a 7 1/4 diff I’d guess with small bolt pattern, all of which is long gone now

Rear bracket is installed wrong and too far forward.
Doesn't look like something that comes in a kit either. Is this the result of someone's cobbled-together redneckery?

Thanks.... That’s what I was worried about..... looks like I might be replacing the shackle mounting point, if you have a chance could you take a photo for reference for me if no one else chimes in
 
Here is a couple photos showing the offset from the frame, hard to get a photo of with the leaf pack in the way, but yea it definitely looks like a home made offset, which is probably why its located wrong at the back

Second photo is the inside of the frame, first photo is the outside of the frame with a measurement roughly showing the overhang from the frame

Agreed. The new spring hanger should be in the same location as the stock piece if the same length springs are used. I would cut the pieces off and trim the channel so the bolt hole is in the same place as the stock piece.
 
I may be completely wrong on this, but it seems to my admittedly foggy recollection that the kits from Mopar used an offset hanger for the rear mount.
 
This is the way the US Cartool kits look on the rear.

.......
The bolt goes through the rail. I wish this car was mine. LOL

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.
 
Here's the Magnum Force set up. See the collars with the plates attached? They go through the hole and the plates welded to the rail. I like the way the US Cartool set up works. It bolts into the original holes and then is welded to the rail. mopar rear spring relocation kit - Google Search:

Found this, it's a home done job, but it will give you an idea.

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
