This is the one I use when air is a problem:

So I looked at what I was working with a came up with a idea:



As you can see I put a big bolt through one of the holes on the crank pulley,put a bolt through the tow bracket at the front of the car, and attached a chain to the bolts via nuts.

After using this method the bolt came off with a couple firm pushes from my foot.
I don't know if someone else has thought of this before since it's so simple but anyway I wanted to share this with everyone so that you all wont end up ruining your harmonic balancer with channel locks like I did.
Hope this helps.

yep. use a breaker bar with a 17mm socket, remove the flywheel dust cover, and use a prybar to keep the flywheel from spinning while you loosen the bolt
