The bit that secured the right end came off a while ago. I want to fix it, but there is nothing inside the hole to glue into. Can’t completely remove it because the “anchor” on the left side is still attached. Hardware stores are no help (not surprised by that). Removing the shower unit isn’t an option. Likewise, I want to avoid cutting or drilling the fiberglass.
I was hoping there was a cap I could put on the end what would wedge in the hole tight, and that plus cement would permanently reattach it.
