Just put the flywheel on the crank - unbolted - and keep spinning it until the bolt holes in the flywheel line up with the bolt holes in the crank. Make sure to use some teflon tape on the bolts prior to install.
of course murpheys law will come into effect here. you will hold it up to the first set, not match go on to next and so forth. then come to last set and it will line up. if you would have went the other direction first, your arms wouldn't be so darn tired from hold up that heavy azz thing.
