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.
LMR is a great company with great products. I recently purchased the Gibson Catback exhaust for my 2015 Mustang Ecoboost and I love it. Easy to install, great looking tips, and best of all almost half the price than competitors systems. My main reason I decided to go with Gibson was because off the reputation and because I think after searching all the exhaust systems, their exhaust system is probably the best sounding one. No raspyNess what so ever you expect from a 4 cylinder exhaust system. It's a nice low, deep tone.
