a couple questions......


does anyone know where i can buy these instead of the dealer? what i'm reffering 2 is the "channels" on the roof. i don't know if that is the correct term, so here is a pic....



^basically the extra molding on the roof!


now does anyone know if i will have 2 modify the roof or not? my guess is that they 3M tape on?

any advice/info is appreciated. thanks!
