Leaf Spring ID

Good info, thank you.
I have now talked to the guy from whom I got these leaf springs, and he says he bought them new trough a DC dealer we had here in Sweden in the early 80´s. Ordered as a set of SS-Springs for the 3000 lb stick cars. (the #002-003 we better know them) He had a ´68 340 stick Dart at the time, and run MP
Is it may be these springs had another # painted on them, but also the # showed in the pictures? I shall carefully remove the paint on the main leaf and see if I can see something...
I´m going to use them in my ´68 SS/B tribute build.

Thank You
Stefan
