Need kohler 84679 float valve

[JeffH]

For Kohler Rialto toilet. One whacky contraption I tell ya. Can I buy this somewhere other than direct from Kohler? I figure not, but just thought I'd throw it at there....

Unless it is different from most Rialtos the Coast 1B-1-X replaces it. Just cut off the clear plastic tube from the fill valve to the opening in the toilet, and insert the one from the Coast valve into it.
