I would try using a magnet to get it out one of the oil pan drain holes. Then you could use a magnet and drop it back in place through the distributor hole. It's the not ideal way but it would save you from pulling the pan. You wouldn't be able to keep the retainer on the shaft, and everytime you pull the distributor it will most likely unseat the shaft. My shaft retainer moved, so whenever I pull my distributor I have to reseat the shaft in the pump. Fortunately I don't have any more engine mods planned, so I won't be pulling the distributor any time soon...hopefully. Good Luck
