Hi just wondering if anyone on here knows where to find, or mabey has a couple older brake rotors for sale? I've got worn down teeth on mine and am having a hell of a time trying to find replacements. They are the older 40-2 sprockets with the double key bore for a 99 argo vanguard 2. Or is possible to upgrade to splined bore rotors? It sucks that argo doesn't make parts for older models anymore
