I have a customer with a 80 chevy truck cab that never had ac in it wanting to swap it on his 76 with air. He's wanting to find a donor system to swap everything over. Will the 81 up systems retrofit to the 80 back trucks if he takes the firewall system out of let's say around 84 and uses his engine/doghouse parts or is he in for a disaster? I don't want to remove what he is asking for and have to refund his money when he brings it back in a week lol I wish I had saved more of the 80 back parts when they were easy to find because 81 up trucks are about all I have left in parts trucks nowadays.

As far as the cabs go, I'm not too sure. Why not just use the 76's air?

All of the stuff under the hood will swap over, if everything is used from the same era truck. I think the matching harness and HVAC controller will need to be used as well.
