Oldie, Raybestos and Dorman seem to be the best numbers for the rebuild kits. My single master is 1.25", all four rear cylinders are 1.5", the fronts are .875". Yours may be different diameters. I could not find an exact match for new front cylinders so I did the rebuild. I soaked the cylinders in muriatic acid and then honed them, all leak free. Rear shoes for mine are not available but had lots of lining left so I cleaned up the one side that had been leaking, other three wheels were all dry.
