I think this is just a matter of a simple "bolt-in".
The only differences in floor pan exist between the 2 dr and 4 dr models AFAIK, so everything else should simply swap.
The bigger challenge I have found (in the past) was tossing a bucket seat into a bench seat car. In my case (if I remember correctly) that goal required me to drill a couple of mounting holes which already had the cutout in the pan (where the reinforcing plate is), but simply did not have the holes punched through.
