Swapping E & B to A

Hope I can get some help. I have a 72 Dart Swinger I'm redoing. Am going from auto to manual, bench to bucket. Now the questions, Is it possible to use a 70/71 Cuda or Challenger 4 speed console in an A body? Are brackets available for this swap from any vendors? Next question, will B body seats work in the A Body without any major alterations. This is my toy, I'm not trying for authentisity, just a functional, clean looking swap. Thanks for any help, this site is a Godsend.
