ok so i finished up my shaved door lock kit today but in the process i broke off both of the window channels that are inside the doors. has anyone done this or know if they serve a major purpose. Im afraid of either 1, when the windows go all the way down they will go off the normal channel and not get back in. 2, if the windows are all the way down they will rattle like hell inside the door and possibly break. Anyone have experiance with these or know any usefull info?
