Here are some photos of the door pull strap on my unrestored 289 cobra. The strap has a sewn in loop at each end and is then is just looped through itself at the end loop around the side curtain ferrule. I have seen a couple of other unrestored 289 cobras that had the same/similar configuration, but I have not seen original shelby factory photos close up of this area.
-sorry for the double post-
