The crank bolt on my '89 was tough, but two of us did it.

One guy goes underneath the car and removes the little dust cover that covers the flywheel. Stick a huge screw driver in there and have that person hold it. Luckily we had a closed end wrench with the perfect dip in it to allow it to go onto the crank bolt and stick out the top of the engine bay with lots of room to move it. We then took a good 3 or 4 foot long piece of exhaust pipe and put it on the end of the wrench. It came off in one big push.

Be careful when you do this!!!

I damn near lost a finger when MyLittleBlackBird and I were doing the crank bolt. The punch I was holding in the flywheel slipped and wedged my finger between the punch and the frame. I got out of it without broken bones or stitches, but it scared the hell outta me.

yes, i wouldnt even use my hands... prop it in a place where its going to catch, and then duct tape it so it dont fall out

We used a huge flathead screwdriver. My hands weren't even close to the flywheel...but none the less do be careful...
