1966 Barracuda Interior Braided Edge?

Hey guys! I am here trying to figure out how and where i could find this edge that is coming apart slowly on the inside edges of my 1966 Barracuda...

Heres a picture since I am unsure on how to describe it...


Any ideas where in can find it? its pretty much the same all across the borders of the doors. Also anyone happen to have a kick panel? pretty sure you can tell why :p

Any and all help appreciated, thanks guys!
