92 roadmaster climate control unit in 91 model?

I feel like I saw somewhere that it was possible to put a 92 model climate control module in a 91 model that also has climate control to gain the ability to control where the air is blowing out of (feet or body). I can’t seem to find the post now, but does anyone know of this is possible?

Should fit unless the 91 is manual, then all bets are off.
