I hope I posted this in the right place. I stopped at a spring shop and they let me dig in the dumpster. I pulled out some leaf springs with lables on, along with the numbers, they said Made in the USA. The guy there didn't seem to know what kind it was other than it was high carbon spring steel. I don't know what the numbers mean either. I thought someone here would know. The first one says 60R10-33. The second one says 250R262-33. And then I got two coil springs from a Dodge truck that are 13/16" in diamiter. They are supposed to be new. Any idea what they would be? Thanks - Jerry P
