This is a short how-to video on how to instill side window louvers. We are installing the louvers used in this video on a 2009 limited edition Ford Mustang GT500KR signed by Carroll Shelby himself! We mainly put these on to show the install and will most likely take them off in a month or two to keep the Shelby original. These louvers can be purchased on most muscle car online parts stores. Since we did not get this one sponsored, we will leave it up to our viewers to choose the right louvers for their vehicle. Side louvers for muscle cars especially, have been around since the 1970's. They have been in and out of style a few times since then. Louvers are really up to each of the vehicle owners taste.
