How Hard Is It...........

Were good with the mechanical abilities. Just last week I had the car on all 4 jack stands so that's no problem. The original bell housing is cast iron/ steel so I don't think there's that much weight deference. We can get a torque wrench but the thing with the crank alinement has me worried. How hard is that to do. What kind of tools are required for that? I know you need a ring spacer around the front bearing retainer to make it fit the hole in the bell housing. If I get that spacer do I need to do that alinement thing?
