I have a 2000 Grand Prix GTP, and due to rust and old age, the drain plug on the supercharger snout has been stripped while trying to change out the supercharger oil.

Anyone have personal experience on how to remove a stripped plug successfully without damaging the thread of the S/C? I know that there are stuff out there to remove stripped screws/bolts, but I have no personal experience.

Any thoughts will be helpful! Thanks in advance!
