[V8] Climate control swap/changeout

[NIck Miller]

Does anyone know if its possible to ditch the 90/91 gm climate control stuff
for the later 92-94 stuff?  Like, the dual zone climate control that looks a
lot nicer, and less cheasy/tacky, and likely breaks less.

Ok, maybe it doesn't break less (its an audi..) but it looks less tacky!

I'd be interested, since I've nothing better to do till my car is put
together again!
