It's will be the same one and steel. If john Deere still sales the part. It means it's left overs from ones that didn't sale from back when these were built. For example. In the computer it should say along the lines there are 50 left and out of production since 1974 or something along those numbers and years. John Deere usually never reproduce those old parts at all. Just old production that never sold and still on the shelfs or in the warehouse. Hope this helps. Do you know how much they are? Should come with spring or sold separate but would buy that too.
