To convert a 2WD cab to 4WD you need to cut the floor out of a donor cab, or your existing cab you are replacing, this goes back under the seat portion for the 4WD.
If you need references here is a link for the different humps.

Once removed drop it in over your existing floor and make sure it is aligned.

Mark the perimiter of the cut out floor and then measure in about 2 inches and mark another line inside what you have already marked.
Break out your favorite cutter: cutoff wheel, plasma cutter, sawzall and go to town.

At this point you can secure the floor with 1/4" self tapping screws and used 2 sided butyl tape or weld it in.
