It isn't clear from the photos whether the part is just a washer like flat disk, or if there is material that also goes on the sides of the pins...
If it's a flat disk, I'd look for a nylon washer that could be press fit over the pin. (might need to get one that was undersize and carefully ream out the hole to fit...)
If it is material on the sides of the pin as well, I'd go with BM's suggestion of searching for flanged bushing. Or top hat bush.
