These are Lincoln Zephyr shocks (see our other listing for K model). Original equipment, not reproductions. Cleaned to the bare metal. Housings rebushed with bronze bushings, shafts reground.  To aid dirt and water exclusion highest quality Nitrile seals are used, which outlast originals. Valving is properly calibrated for correct jounce and rebound specs. Painted with a gun-metal grey primer. All rebuilt shocks come filled with fluid and ready for installation.
