plastic bracket supports

My Merillat plastic bracket supports broke and am trying to replace them. They say they are no longer made. Mine had one piece on the back side that fit in a hole in the back. The newer types have screws, but the back of the cupboard is not heavy enough to use screws. the no. on the old part was 32-012. Was hoping there was some one that had some that they had before or still had some of the old type Carolyn. Hope you can help

The one person said she glued it back that was broke and then put a hose clamp on it. What works better is to usr strapping tape, like what you use on packages, wrap it around several times from the back of the clamp to the front. It covers it much better than a host clamp after you glue the broken pieces.
