Just another tip, if you are worried your doors will have to be aligned again try this, I drill through each hinge in 2 places with a 1/8 drill bit before removing any bolts, that way when you are hanging the doors I grab a couple short 1/8" pieces of welding rod bent into "L" angles (just so I can push them through the holes that have been drilled) and then put in all the bolts and tighten and pull the rods and your back where you started.
