AC Swap Question

[BHyatt]

I have been spending way too much time at the local pick-a-part lately. I have been noticing that there are a lot of 85-87 trucks with complete AC systems still on board and many are still holding pressure in them. Can I swap one of these systems into my '71?

I am sure that everything could easily be swapped onto my engine and mounting of the condenser would be fairly straight forward. I suppose the big question is whether or not the evaporator coil will fit into the cab.
