Replacement for Diving Board Springs

The diving board springs for my circa 1960 swimming pool have rusted and fallen apart. I would attach photos of the board and springs but I don't seem to have permission. Instead I will try to describe them. The springs are two separate roughly U-shaped leaf-type springs that attach to the deck at the bottom of the U and to the board at the top ends of the U. I am looking to replace these but can't seem to find a source for these parts. Does anyone have a recommendation or suggestion for a source for replacement springs of this type?

Thanks

John
