Rusty Body

Ok ive been looking at all the body work the car is going to need. It needs the trunk pan replaced, both rear fenders need replaced, both rear rockers repaired rear deck between glass and trunk, and front passanger inner fender not to mention the rust under the vinyl top. My next question would be would it be better to find a good roller and swap everything over from my car or get all the panels done to this car. Just looking at my options.
