When I replaced my steel body with a fiberglass one I found it to be pretty easy. Granted I took mine off in sections but i had to go through the motions of disconnecting everything. You could disconnect everything and just lift the body off the frame with 4 or so people put it to the side and have access to everything you want to work on, thats what I found to be the greatest part of owning a jeep.
Good Luck.
