1968 Formula S Barracuda Leaf Spring Identification

Thanks for all the responses. I know springs are a pretty simple issue. but the reason I'm asking such a mundane question is that I'm not sure if I have the original springs. Because a 7th leaf was added and the work looks sloppy. I'm not sure what else may have been changed. Also, I bought a leaf spring rebuild kit from Mancini Racing and there are enough zinc plates and plastic isolators to do 1 1/2 springs. I'm not sure if I needed to buy two kits or my springs have been changed. Anyone had the same experience with the rebuild kits? I haven't had much luck searching the net for specs or drawings etc.
