My daughter rescued a bookcase with shelves from the curb but it has no shelf supports. The shelves have 2 grooves along their undersides I'm guessing for wire rods that fit into the holes in the sides. I'm trying to help her long distance. I sent individual peg-style shelf supports but don't know if they would be too big for the holes. Any advice what the rods are called and what size they might be if the ones I sent are too small? I googled but could find no info. She has limited access to a hardware store or tools.
