Hey -- What do you call this bit

So on my Wildcat (Conv) when you open the door there's a rolled vinyl edge, near the striker pin. It's not part of the rear side panel, as I recall it's actually stapled in place. It goes from the floor to the top of the side panel/quarter window. I took a pic of the passenger side. The driver's side is beat to death. I'm not sure if I need to have it made or if I might be able to get an Impala piece to fit??

 

I believe what you are referring to is called Door Jamb Wind Lace

 

Thanks @Mike Trom -- it was killing me as it was not in any of my manuals
