Removal of Underdash Portion of Air Conditioner

[RQ-B1899]

I am trying to remove the underdash portion of the air conditioner in my 1972 Avanti II

and I don't know how to do it. (I don't even know the proper name for this part!!)

Surely I don't have to cut the console to remove it.

Also, what are the relatively small flex hoses that run through the front part of the console?

Thanks in advance for your help!!!
