Which leaf spring?

Thanks!
More pic in "my pic". It is the fabled Pontiac Super duty scoop " Ford dump truck scoop. Figured it is about the only scoop available in 1965. No one would have been able to get there hands on a max wedge scoop in 65.


On subject. The SS springs do ride a little rough. But I do not have much to compare them to. As my original springs were like riding in a worn out caddy.

Man I like your car 604. I love that scoop!!.
