What is the best way to fix cracked sandstone slabs ?

My wrought iron railings corroded enough over time to break the sandstone slab around the legs of the railings which were set in with molten lead. What is the best way to fix the slab short of replacing them?

    I was thinking about possibly using an epoxy product to relain the stone and topcoat the whole slab.

    I'd try to fill in with concrete very smooth

    William, your idea to pour epoxy into the craters sounds as if it could work. Clean the slab and sand the iron posts and background. Coat the end of the post as well as the hole and follow the directions for drying time. You can leave the epoxy clear, or add a little paint so you can build the connection back. Once set, thre epoxy often is as strong as the original bond. Best wishes ☺️
