Hi Goody, Rear Seat Frame??   

  some cars had four of them. some had two. (not cuda/challenger specific)

[Street_Challenged73]

I'd say some rusty wheels, but that'd be using the redneck standard for the laws of physics if some had 4, while others had 2.

For my real answer, it looks like a photo of the trunk lid tensioners/torsion rods from the side, but I don't think they ever used anything past two for those.
