mrboyy17 posted a link regarding bushing replacement. I don't think that's what you're referring to is it, Derrick79? Of course posting a pic would be the best way to get a good answer, but if you can't you may need to describe the damage a little better. You say the rear body mount has gone bad. Do you mean that above the bushing you've rusted away to nothing? If that's the case you may still rather try to fix it than do a cab swap. Is your cab good enough for your needs otherwise?
