Are these Super Stock springs?

['74 Sport]

Can anyone ID these springs for me? My son Aaron bought these with the understanding that they are Super Stock springs. I've been trying to hunt down some replacement bushings, but the SS bushing kits I found are not the same size as the ends of these springs. I cannot find part numbers stamped on them anywhere.

How long have SS springs been around? Could they be early versions? How many leaves are typically in a set of SS springs?

Can't see a whole spring, but it doesn't look like there is as much arch as the springs I just got for the Duster

I've been told there should be numbers near the end of a leaf. Can you post a pic of yours showing the numbers?
