I need new leaf springs for my 12-second 401 powered Spirit. I was going to buy Eaton's, which I would rate as top quality, but checked with Kennedy American for comparison. His springs are half the price of Eaton, and American made, although he doesn't know the manufacturer. They are not Espo, which I want to avoid. Has anyone purchased these springs from Kennedy? How do you like them? Cliff Danley First Coast AMC Jacksonville, Florida
