In fact. If the cores are good and correct, save them. There's still some places you can get them relined. Rochester Brake and Clutch, and Porterfield are two if no one is closer.
Too many times now the aftermarket 'consolidates' or cross list shoe frames (metal part of the lining) ands sometimes its OK and other times its not.
Generally the frame designation number stamped on the metal. Its a trade industry number so recognized by all brake manufacturers.
