Drag chain replacement parts?

Do y’all know where I can find the drag chain for my x-carve? I found this one but my model doesn’t have these X-Carve Drag Chain Kit | Inventables

My model has these X-Carve Instructions: Drag Chain

I increased my shapeoko2 / xcarve upgrade to 1000mm and bought one on amazon. Not this particular one, but just an example.

Hardware stores sell all kinds of metal brackets with angles and holes in them…another example
