I have a 2005 Ford Mustang. I have been on websites such as Newfordparts.com and others and have yet to been able to find this piece of window striping/moulding? It's the part that goes inside the car/door jam. I have an arrow pointing where the molding is on the attached picture. Any help would be appreciated. I'm getting tired of the lake that grows in the back of my wife's car everytime it rains....

 

If www.rockauto.com or www.latemodelrestoration.com doesn’t have it, then check your dealer or junk yard. Good luck...
