In F150 rear window for a month, still firmly attached. There was a small hardware issue with a 36" road bar (same brand, should have fit) I got from an old car. The groove they put the screws in was larger and easily fixable at the hardware store. Depending on the size (depth) of the bar. Vertical mounting will require some understanding and realignment of the mount, although tilted glass shouldn't be a problem.
