Swapping A/C to a non A/C car... and vise-versa

I have a 71 Demon that is a factory non A/C car. I also have a 72 Dart that has factory A/C.

How difficult would it be to swap everything out so the Demon has A/C, and the Dart will not have A/C?

Momma says that the 72 Dart must go... but I would like to get some good items from it before it goes away!

I suppose it would be a great help if I could locate a manual that would cover the removal and replacement of all of the parts I would need to swap out.

Thanks in advance!
