I tried to post a link to a picture but im new to this forum and it wouldnt let me, i have the rear brake / footrest assembly off of what im told was a 76 ironhead. the brake is missing the round disc that the front ferrule of the brake cable is held by. ive tried looking on online fiches for it but cant find it. does anyone know what this part is called and maybe where i can get one? i can email a pic to anyone willing to help out too. thanks.
