Brackets on Dana 60...what are they?

[ChargerPilot]

I bought a 1969 Dana 60 that had these brackets on it.

Can someone tell me what they are and what they might be worth?
Thanks,

They go between the spring pad on the housing and shock plate for adjustable traction bars.What are they worth,without the rest of the pieces,not much.
