Unless you suspect something is broken in there, you are better off just freeing up the stuck clutch through tried and true methods. There is at least one method posted in the last several days using jack stands under the rear axle and shifting the trans into second gear. Start the motor and rev it a bit then hit the clutch & brake simultaneously. Just be certain the car and stands are on firm footing and the rear tires are clear to spin before the attempt.
