Best way to do this job, which I have done several times myself (Mopar rear leaf springs are notorious for being soft with age), is from your setup, leave the leaf spring in place, unbolt the center pin using a large C clamp to hold them together until the bolt is out, remove all but the mounting pring (it has the eyelets and mounting brackets), then take the other spring apart the same way, and replace all the other leaves in place of your old ones. I usually find a longer bolt to get all the leaves lined up and then C clamp them together, pull the long bolt out and replace the special centering bolt back in place, then bolt everything together, stick the leaf clamps back in place. This way alleviates the slight differences, all the leaves have to be is the same width and the mounting remains original.
