i notice that my 2000 mustang that i just bought has alot of the vent plastic panels that put the air into certain directions has alot of loose or broken panels. how do i get the plastic panel off. i notice it has two star screws at the bottm of the panel. i took off the shifter panel and took out the two screws. dtill nothing . where are the rest of the release screws or clips . can i repair the loovers on the vent after i finally get it off the car?
