A/C and heater push button controls removal

Hi everybody,

I just bought a 1971 dart with AC and the controls won't work properly.
I wanted to remove them, to be able to inspect and repair everything, but I'm afraid of breaking anything.
I loosened the two screws in the top corners of the panel, but it still seems like it can't be pulled out.
Do you have any recommendations on removing the radio and ac controls?

Thanks in advance,
Dan
