Any tried A/C Setup from 1980's M_Bodies?

I've always thought that M-Bodies had a lot of Swap potential for
1960-70's A-Bodies. I have pulled brake, rears, suspension, electrical, fuel, engine, manifolds, etc,etc off of an '85 5th Avenue & put them on a couple of '67-68 B/Cudae.

One thing I'd like to try (since I have it) is to pull the a/C system from the 5th Ave & install into my '67 B/Cuda.

Barring interior vents(& maybe controls), this looks pretty straightforward. Has anyone tried this successfully?
