Split bench seat springs

I posted a similar post a while back. Could not locate the springs. Does anybody have any idea where I can find these? They connect the coils in the seat backs. I’ve searched everywhere. The only ones I can come up with are these for a Corvette. But they are rather pricey and i’m not sure if those are the same.. I am going to need quite a few for my seat backs.

I need to rebuild the back rests for my 64 belvedere also. I have not purchased any yet but I think the local Fleet or Menards should have springs. They both have a good selection.
