Fastback Barracuda Folding Rear seats-damaged?

I have a total of 3 folding back seats out of 68 and 69 Barracudas. Every single one of them is damaged in ways I can't make sense of. The good one I used had the frame rolled in around one of the hinges, I was able to disassemble it and hammer it out then put it all back together. The other two seats I have have the rod that actuates the cam lock all mangled and the hinge plates on the seat back all torn up.

What on earth did people do to these things? Are most of them like that or did I just get lucky.

50 years ago people opened them up and threw or dropped things in there. Sometimes the spare tire after changing a flat because you were too pissed off and greasy to care.
