2014 Cobalt 232 Swim Step washer bumper question

[spen5151]

Hi Everyone,

Looking for some help, I searched the forum and the internet but could not find anything. I am looking for a part number or part name for the bumper washer that is screwed into the swim platform. I included a picture with an arrow to the part I am asking about. Mine have deteriorated (the rubber broke down completely on one and the other is on its way out). I need to replace both of them. I can call the dealer and ask, but I was hoping maybe someone on here would know.

Thank you for the help.
