I just did mine on my 5.2 1995 Dakota. Since the WP is going bye-bye anyway, I didn't care if it broke. all I did was take my biggest Craftsman screwdriver and pound it in to wedge it between the pulley and the WP housing. It then held the pulley tight so I could remove the nut with a large crescent wrench. And the old WP was fine for a core too.
