This is the door latch mechanism from inside the Drivers Side ( LH ) Front Door, taken from a 1956 Cadillac Fleetwood. Will fit 1956 Sedan's as well as Fleetwood's, and may work for 1955 as well, but please verify it is correct for your application before purchasing it. This is in working condition. It needs a good cleaning and some new oil / grease but otherwise looks fine. Some minor surface rust, but nothing much. Comes As Shown, As Is.
