This is the black molding that runs along the windshield pillar and roof of your Mustang. These are normally faded and pitted from the weather. Don't put old trim on a freshly painted car. Late Model Restoration has the new roof rail moldings you need to make your late model Mustang look new again.
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
