This is a pair of rear end axle shafts. These will fit all 1957 - 1964 Cadillac's, except commercial chassis cars, but please make sure they are correct for your application before buying them. These are in good used original condition. I see nothing wrong with them at all, the splines are all good, no marks that I can see. Were removed from a non running parts car. Sold As Is, As Shown. Please let me know if you would like any other pictures of info. Thanks
