Pivot rod for bifold doors

A home owner from USA says:
Hello customer care. I am Doug Woods at 919-309-5563. I have six bifold doors that need a new threaded rod installed at the leading edge of the door. Please refer to the photograph within the attachment and get back to me if you have a part that would work for this. Thank you very much. Doug Woods

The best I can make out from your photos is that the guide pin looks similar to our 21-044, while the threaded pin looks like our 21-002. Please compare these to your own and let me know what you think.
