Removing the Air Evaporator from an 86 4KQ

[ReD4000QuATTRo at aol.com]

Hey Quattro List!

I am removing the AC in my car since i won't be needing it in sunny San Diego, CA  =).  I had a quick question for anyone who has done this procedure.  How do you remove the blasted Air Evaporator from behind the glovebox?  I do not see any screws, nails, superglue, or tape on the box...but it still will not let loose.  Are there any special techniques or tools needed to remove the beast?  Any help would be appreciated!
