Depending on the size of the clutch disc, there will be either 6 or 9 bolts holding the pressure plate to the flywheel. You'll be able to reach a few of them through the opening at the bottom of the bell housing, and some creative tinkering with a ratchet and some universal joint sockets through the square hole in the bellhousing can usually get the rest of them out. Once the clutch disc and pressure plate is removed, there are 6 bolts holding the flywheel to the crankshaft. As a last resort, remove the oil pan and unbolt some or all of the connecting rod caps. That will let you turn the crankshaft a little for better access to the clutch bolts.
