Being in the position youre in,,yes,theres bolts that you wont be able to get to without rotating the motor.
If youre not trying to salvage the bellhousing too,,take a short handled 5 lb. sledge hammer with you and break the bell housing away from the clutch/flywheel assembly.
A little on the radical side? Yes. But, it'll get you to the parts youre trying to save.
