This is 1 connecting rod for 1955 - 1958 Cadillac motors. These will fit all 1955 to 1958 Cadillac's. Used original condition, dirty and greasy but otherwise OK. These are still the original size, and will probably have to be resized before use again, but being original size there is lots of material to work with. There are no scrapes or bad wear on them, they are used but look to be good still. Sold As Is, As Shown
