Stereo Swap - need advice

I am trying to swap the stock AM/FM cassette deck in my wife's 2000 ford windstar van. How do you take the plastic shroud that surrounds the radio and heater out without breaking it? to expose the screws to remove the radio?

Response:

The shroud just snaps in and out. Use a plastic pry tool and pop it loose to expose the stereo mounting screws. Here is the wiring in case you need it for the swap.
