Rear leaf spring shackles

Perches are at 43. These were new and assembled on a 71 demon. The spring , hangers and shackles were all together. I assembled it on the diff and installed in the car. I took hangers, shackles with spring all assembled and swapped it today and it seems better. still a slight lean inward equal on both sides but the bushings not in bind anymore. seemed the other way the bushings had a slight bind. ???
