1990 ccu into 1985 W126?
 

So today I went junyarding and found some very nice cash for clukers victims. (Including my own). Anyway, I found a really nice piece of wood climate control wood from a 90 420SEL and and the climate control was in like new condition also. I'm pretty sure I can put the wood trim in my 85 300SD, but has anyone put a new climate control unit from generation 2 W126 into a generation 1? Thanks

Won't work...

Completely different systems.

I was afraid of that.
