These rods are all untouched stock rebuildable cores, with original rod bolts. None of these have been magnafuxed. All rods are number stamped and in kept in their original engine groups. There is one set of 1971, two sets of 1973, one set of 1974, and three sets of 1976. I personally disassembled the engines and all the bearings were in good shape. All of these came out of either Electra's or LeSabre's, not GS's or any other type of Hot Rod inCARnation. I am asking $40.00 plus shipping per set (8 rods), or $200.00 plus shipping for all (56-rods). Larry
