Ok, your going to take a razor and jam it between the wood and plastic driver. Go around the whole plastic circle. Some places will be tougher than others to get the razor deep enough. You will need a stronger blade as I broke a few off. Just keep going around the circle and eventually if will just come out. Dont get discouraged at what the wood looks like when your doing it. Just keep thinking that you are going to be able to sand the wood and restain if you want. It really just takes time and patience.
