I am doing some slight dissasembles and clen-ups around the interior (I can provide tutorials and pictures!), now I need to replace the AC unit (above radio), how do I slide it out?

 

Reach behind from the radio hole and push it out.
ATTN. It would be a good idea to use a pretty heavy glove or wrap your hand in a rag. Sometimes they get kind of stuck. Then when they release you will scratch the H*** out of your hand and arm.

 

Thank you very much for the warning..!
