Anyone have the 100 Series roof dimensions handy? Specifically, I am looking for (a) the width as measured from the inside of the channels, (b) the width of the channels and (c) the length of the roof from the back to the top of the windshield and from the back to the front edge of the sunroof. Is there any tapering from front to back or is equal width all the way down? I need the measurements in order to compare with my 4th gen 4Runner for installation of a roof rack that is made for the 100 series.
