1957-59 Mopar 12" brake drums these came off 57-58 Chrysler and Desotos, may fit other years besides 57-59.  Do not fit Imperials.  I have fronts and rears, let me know which one you want, have multiples of both. These are used brake drums pulled from parts cars, at minimum need cleaning, may need turning.  I have no information about them other than that, the parts cars they came off of had not been on the road in over 50 years
