Dash Frame ?s

I have a '71 Dart GT (Swinger). I would like to do something different with the cluster. I don't want to mess with my original cluster/dash frame.
I've located a '70 Duster standard dash frame. Will this frame fit into my '71 Dart GT (Swinger)?
Also, what is meant by standard dash frame? No A/C controls? My '71 Dart GT has A/C controls what can I do?
