1968 Formula S Barracuda Leaf Spring Identification

I removed the leaf springs from my 68 S B-cuda and discovered that a previous owner made some sloppy modifications. A 7th leaf was added using a leaf from some other vehicle that was sawed off to fit and the "now to short" clamps were made to fit by welding a bolt across the clamp. I want to take the springs back to the original 6 leaf configuration. Before I start I was wondering if anyone has any pictures, drawings, specs or any reference material I can use to properly rebuild these springs. Thanks in advance.
