Replicate? No, Ron go with the idea of a stiffing piece glued to the back. Just a matter of finding an adhesive that will bond nicely. I'm surprised JB didn't do the job but the narrow gaps may have been the problem. I would just align the pieces and glue from the back with something like a thin stiff piece of metal. Something like the edge of a wood ruler sounds like an excellent idea. Good luck and glad your back.
