If you replace the pickup the screws are Stainless socket head cap screws with mechanical lock nuts securing the magnet. It is somewhat dificult to do without the distributor removed. Adjusting the Air Gap between the Reluctor and the pick is tedious and must be precise or the trigger signal will cause irratic ignition and misfiring. Use a brass feeler gauge or baring that try a matchbook cover .015 thick. Doing this right is not as easy as you might think.
FYI the new screws and nut come with the replacement pickup from MSD. It is difficult to clean the remaining adhesive and silicone potting material out and replace the wires without being able to spin the advance mechanism to access the area. Good luck
