Carb for a 1963 225?

Hi all,
I need a new/rebuilt carb for my 1963 Dart with 225+automatic. Anyone know which years will fit "bolt on"? Also, will a carb from a manual trans car fit? How about from a 170 engine?
I have a guy who will do the swap but I'd like to help him a bit with this info...

Thanks,
Tina
