What "makes" a 66 Barracuda a Formula S ??

Why did you scrap them? I'm still running the original springs on the 66 and 68.

I disassembled, blasted these swap meet 340 springs and put them back together with new insulators and zinc interleaves for my 63 Valiant. Pretty much look and function as new. I did paint them before installing them. They, too, are six leaf springs.
