No those pieces are just the rear section of the frame. You would need a much longer section which im pretty sure no one makes. Either way the body has to come off for a proper fix so you would be farther ahead to just swap in a new frame. I would find one cheap, get it blasted, coated in a good chassis paint like POR-15, redo all the brake lines and fuel lines in stainless lines and then swap it. All of this could be over a length of time to make it affordable. That way everything is covered and a little peace of mind is there for preventing future rotting issues. If the frame is really rotted that bad I honestly doubt that the floors are solid. Mine looked solid but when I pulled the carpet up huge chunks of the floor came with it :lol:
