There has been some debate on this one. Some people say that a re-arched spring doesn't last. I would think that it would depend on your local choices. If you have a spring service nearby that can make new ones, that may be your best choice. The old truck suppliers can get new originals. There is Bill's Truck in Courtice and Antique Chev in Oakville. We have a good spring guy in Bolton here who I used. He is very reasonable.
