Suggestions needed
 

My son has 98 Dodge Ram 2500 24 Valve Cummins. Crankshaft Position Sensor took a dump. Should be a simple fix. Wrong. Pulled starter, no problem. Now, the bolt holding the sensor bracket in place. Will not move. Soaked it, heated it nada. Used fluted external bolt extractor, now have just a stud. Anyone have this issue before and have any suggestions?
