Anyone use a whole floor panel?

[Pinchecharlie]

Have a guy who's going to help me do rust and he suggested doing the whole floor. Said after labor that it was faster and easier with a whole new floor. He's done a bunch and he gets paid so I trust his opinions but I wonder if they fit worth a crap? He's used to old ford and early hot rod stuff. Anybody use a whole new floor stamping for 60-66? How's it fit? Would you recommend them? My trucks bad from rocker in about 2 inches of floor an from firewall to back cab.thers a few other bad spots in the floor at random too. Thanks charlie
