I have an 01 Cobra and am trying to change out the clutch on it. However, I cannot, for the life of me seem to get the 2 bolts at the top of the bell housing off. I am using extensions and swivels and nothing seems to be working when coming at it from below. Do any of you have suggestions on how I might go about removing these damned things? It's the Tremec 5 speed.

Thanks in advance
