I'm planning on swapping the engine and trans (318 and 904) from a 1971 Coronet into my 1968 Dart (Dart has a slant six).  Other than the engine and trans, what parts am I going to want to keep?  (Can I still use the radiator from the Dart?  Will the mounts from the Coronet fit my Dart, or will I have to buy a kit?  etc.)

Below is are some pictures of the Dart.
