Need some help controlling body roll
When I first saw your photos I thought that's not an a body 8 3/4, those shakels look like offset shakles with one side on backwards, you have a 318 car probably did not come with a 8 3/4.
Here is a photo of an A Body 8 3/4
My guess is whoever swapped the rear in had to use the shakles to make up for the perch being in the wrong place and raise the rear as others had said to allow the tires to clear.
