Hi:
Not to sound crazy, but are you turning them the correct way? They need to turn to the left to come loose. If that is not the case, (I'm not sure how much access you have) but try using a 1/2 inch drive breaker bar. Maybe the extra leverage will help.

PS: If you still have trouble, let me know.
