Anyone use one of these a/c systems before?

I was thinking this may be more budget friendly than replacing a entire cab plus less labor intensive. the housing i live in(military) wont fly with having parts trucks laying around so i cant easily do a cab swap. But didn't know if it was a good set up or not. Also i wanna eventually switch to a serpentine set up so im not sure if ill run into future issues with this.
thanks for any help

Vintage Air is revamping their direct fit system for our trucks pretty soon. I would imagine the new kit should be ready by the summer. Changing to a serp setup isn't a big deal; the only thing that will be affected is the compressor if you change the whole system.

Do they have a option for year because the one shown has a 81-87 dash piece and a not a 73-80
