In retrofitting the newer seat into mine I am leaning toward using a length of 2"x1/8" steel flat bar below the floor pan that will tie both seat mount points on each side of the seat together front to back just for a little more strength and to spread the load a little. The seat belt anchor points can be tied into the flat bar as well. I might be able to tie the ends of the flat bar into the edge of the original seat mount reinforcement areas too.

Run the seat mount studs from the donor through the flat bar and up into the cab so the stock locking nuts can be used too. Stitch weld the flat bar to the bottom of the floor pan to secure it in place and seam seal the rest of the edge to keep moisture out.
