Light & motion 105 VR port

Does anyone know the difference between the Light & Motion old flat port and the new VR flat port?

I was told that the Nikon 105 VR will work with the old port, provided that the inside of the port is modified slightly. Is this corect?

Thanks

When I asked L&M about it they told me the difference was the gear required to use manual focus. I purchased the new 105vr port...
