Is there a tulip-flower lens hood that will work with the Nikon AF Zoom-Nikkor 35-70mm f/2.8 D?

The front of the AF Zoom-Nikkor 35-70mm f/2.8D (both the hood bayonet and filter thread) rotates during focus. Therefore a petal type lens hood would not be correctly aligned most of the time. Hence ...
