I don't know about the part number, but yes, leaf springs can be restored. They can be re-arched, but it won't last as long as new springs by a good margin, plus, the cost is probably about the same or even a little more than new springs. I've re-arched a good many springs before. It's kinda a lost art. I prefer to re-arch them cold, but some people heat them up. The heated springs really don't last very long at all......well I've never seen any that do. When new springs are so affordable, that's the direction I recommend.
