This is the original hold down clamp for the distributor from a 1958 Cadillac 365 CID engine. I beleive this will fit and work for 1955 to 1962 Cadillac's as well as possibly other years, but please verify that it is correct for your application before buying. This looks to be in good used original condition. It needs a good clean up and maybe a fresh coat of paint, but otherwise it's in good shape. Comes as shown, Sold As Is. Please let me know if you would like any other info. Thanks
