Help needed getting crank pulley off

[spdylude]

I could use some advice getting the crank pulley bolt off. So far I've got the fan assembly out of the engine bay so that I can fit a ~ 3 ft breaker bar on the end of my 1/2" drive wrench. I am having a friend put the car in 6th gear, set the e-brake, and then stand on the brakes. So far I haven't had any luck using this method. When I apply force to remove the bolt; I am able to rotate the end of the breaker bar probably 90 degrees but it seems like the breaker bar / wrench combo is bending and combined with the play in the transmission I am not getting anywhere. Does anyone have any pointers?

My next step is to take the whole damn radiator out so that I can hit the bolt with my 1000 ft-lb impact, but the service manual procedure implies pulling the radiator is quite the ordeal (apparently includes draining the A/C refrigerant for some reason).

Thanks for your input!
