Flywheel bolts are stuck.... help?

[Thor06]

Hey guys, got my engine out and mostly disassembled. I am having one problem though, I cant for the life of me get the bolts off of the flywheel and the nut holding the crank sprocket on.

The block is sitting on the headgasket surface now with a breaker bar on the crank sprocket nut and I was using the 1/2 ratchet to work on the flywheel bolts. When I turn the ratchet, the breaker bar hits the table and I would be able to put some torque on it, but when I try to put a lot on, the breaker bar just lifts the block up. The Haynes manual says to "wedge a screwdriver in the ring gear teeth to jam the flywheel." Well, I tried to wedge a screw driver into the timing belt and balance shaft sprockets and I couldnt find a spot to wedge a screwdriver on the flywheel and none of it seemed to work. So what "gear teeth" are the talking about? Where would I wedge the screwdriver? Any other tips to get the flywheel and/or crank sprocket bolt? Thanks guys.

Oh yeah, we dont have access to a impact wrench.
