Stock Radio Bracket removal?

Hello everyone,
I bought an aftermarket radio that is a direct fit for the factory radio. I need to know how to take the plastic brackets off the stock radio so I can mount them to the new one. Does anyone have any clue how these come off? There are no visible screws. Thanks in advance for any info you guys may provide.

I think just squeeze and pull. I think they just snap into the stock Head unit...
If not try pulling forward or pushing back they might pop off that way...
