Rim eyelets all look pretty much the same from the outside of the rim, but in fact they are specific to each model of rim. So really, your only option is to find a stash of eyelets made for very same rim; and considering the eyelets in question were never sold separately from the rims, you'll never find them. Any extras they had, at the factory, went into the recycle bin when they stopped manufacturing the rims. If you could find a junked rim of the same model with better eyelets, you wouldn't be able to remove the eyelets without destroying them.
