I am not aware those are original. I have dismantled a few beds and I have never seen that arrangement.
I think we need more opinions. But to your question - using the bed strips you have, where can you get fasteners? Maybe someone has a source for those. I have seen them but I dont recall where.

We can debate it here and then I may move this question over the the bed forum.
