From a low mile 1970 Malibu survivor which the brakes were working just fine are these standard 3853549 front drums dated A 30 70 and B 2 70 (January 30 and February 2 1970). These are good to install "AS IS" perfect for a survivor or blast the tops for perfection. These will NOT fit the rears as they are bigger in size and carry a different part #.
