hey - what about torsion rods from a different A body convertible?? 1967-68-69 Plymouth Barracuda convertible Trunk Lid Tension Rods | eBay
Probably would work...if they still enough tension in them.

I bet you could bend them a few inches back in the opposite direction of how the tension is when installed and get the full torsion back out of them.
