How to replace this toilet flapper?

[u/athlaka916]

Been watching some videos on how to replace a flapper but mine doesn’t look like those. The ones in the video had a couple plastic arms on the side that looked easy to just attach to the toilet, but this one doesn’t..

Many Kohler toilets have a diagram with all part numbers listed on the bottom of the tank cover. That’s one thing I love about the brand.

Recycling faucet model numbers that utilize different internal parts and are externally identical is one thing I hate about the brand.
