as for the crown vic, thats a VERY VERY good choice if your not planning on throwin mirrors under the truck at shows, or stock flooring, and already have the car or know of one cheap.
It's basically (for my truck, sorry dont know for slick sides) new rear cab mounts and bed mounts. Nice little swap that could honestly, probably be done in a week if you worked afternoons and the body was off the old frame already. A few friends, little steel and a cheap welder would do for a solid swap with newer car style handling. Works bagged as well.
