I have problems with my "new" alternator. I am trying to get the pulley off the Alt I just bought off Ebay. While holding the pulley with a pipe wrench I can get the nut to turn but the pulley is spinning on the shaft while the Alt turns. The nut is not loosening. Is there any safe way to stop the Alt from spinning so I can remove the nut?

Edit: I couldn't see a way to get that nut off so I am trying to take the Alternator apart in order to find something to grab onto to keep the shaft from spinning. But I cannot get any further than the attached photo. Any place I pry is causing plastic to flex. I can't see how the rest of it comes apart.
