BRAKE CYLINDER INNER BORE SIZE

Hi Guys, Does anyone know if the brake cylinders are the same for both 10" and 11" drums ? I've ordered parts off Joe Suchy and he's being told they're the same but asked me to check it out so any advice would be appreciated. Also it appears that riveted brake linings are no longer available, only bonded ones, anyone know different ?

Thanks from P O'Lara
