1964-66 Kettle wheel treads

[Missippijim]

I finally brought home a red 1964-66 kettle.  Overall, its in pretty good shape for that year.  Does not have the original grates but those prob would not have made it to 2020 anyway.  However, the metal hubs are missing the inner rubber tread.  I found the member GrillGiant and asked if he still had any sets.  Besides him, is there another source for the rubber tread insert?
