Looks like those have the F-code springs. They have slightly different spring rate than the B-codes people use but work the same.

In 2005 when ford changed to the different front end setup they also went to the F-code spring for the rear from what I remember.

Any leaf spring can be altered and modified.

That is what I needed. Thank you. I may just do airbags. The truck is sitting on the springs and I will have to get the yard to move it.

I agree!
But is it my old eyes or maybe the camera lens playing tricks on me that those rear F codes springs look like "W"s, where they are bent UP in the middle at the axle perch?

I thought the same thing in person. But I did not know if that was possible or if they were just that way.

How much is the yard asking for the springs? Have you checked with ATS? Are you planning a conversion to coil front?

I would love to switch both front and rear suspension/axle. But I don't have the time or place. I was concerned about damage to the bottom, the fuel tank had been crushed in. Their price on the web is about $40 each.
