I used a piece of 3/4" X 3" steel. I drilled two holes that matched the puller holes. I used a big nut slightly smaller than the crankshaft OD (maybe 3/4") which I welded to the steel bar. The nut is used to push on the end of the crankshaft while the bolts attempt to pull the flywheel off the crankshaft. I then tightened the puller bolts going into the flywheel, making sure to tighten them evenly. This normally pulls the flywheel right off. If you get the bolts tight and the flywheel still will not budge, hit the center of the puller with a big hammer and keep trying to tighten the puller bolts. Be careful to not allow the puller bolts to go too far through the flywheel, which will damage the seal housing or main bearings.
I have a few more tricks up my sleeve if this tip or the others mentioned above do not work.
