Any trailer Ive had with that type of leaf spring I changed them out to the dual eye type and got rid of the slide. One trailer I was able to just bolt shackles to the bolt keeper bracket that keeps them from falling out and then bolt the new rear eye to the shackle. The second trailer I had to weld spring perches to the rear of the frame to mount the shackles/leaf eye. I would think you should be able to add in a ware plate fairly easy though. We have some hdpe plastic here at work that we use for ware pads against metal contact.
