Need help with leaf spring part number

[69GT]

Can someone please tell me what the application is for a leaf spring with a part number of 3400081?

I forgot to mention, the number is the same on both springs. Does anyone have an idea as to their application? Basically, I'm just wondering if they are springs from a 340 car or not.

I'm not sure there is a wide varity of rear leafs similar to what was available in torsion bars. All the leafs I've seen are either 4 leaf or 6 leaf stacks. Any and all sag with age and need re arched or replaced at some point.

That is the same part number on both sets of leaf springs on my 1971 340 Duster. There are 6 leafs in each set.
