Leaf spring question

Hello. This spring I got my ‘74 Duster out of storage and started working on it again. After swapping out the rear end and replacing the gas tank I finally was able to get it off jack stands. It seems to be setting really low in the back now. I’m thinking the springs are bad but don’t know for sure. I took a couple of pictures of the rear of the spring. Would anyone help out with advice on if the springs are bad or if it’s normal and that I just need to put shackles on it to raise the rear end so my 15x8’s will clear the fender well openings. Thanks

Those springs are shot. Replace them.
