If you are only putting in a trunk floor pan,with no other panels off,its a little weird but do able.I suggest the use of metal bonding adhesive around the top of the spare tire well so that you get a good seal with no warping of the new metal.The rest of it can be safely migged up as the glue cures and the end job is nicer than new in several ways.Just under the turn signals if a place where the factory used"dum dum" this is a great place to put any left over epoxy you have...
