Large Antique Mirrors

Looking for the best way to do it with just two people. This is a 3 very large door (w / mirrors) wardrobe circa 1910. Top I am concerned about the very last part where you have three doors to get hung up and continue, then the bolts to attach. Thinking about packing a belt around the whole thing to keep the doors in place and then setting up to get the door hinge pins in place. Anyone done this before?

As with any project start up from the floor --- the drawers if you have them, next door assembly, you are ready to put up on the spot glue joints firm --- on top of the cabinet - and on the sides if necessary.
