You found the "tool" to remove the radio, (I used finish nails), you might look at how the radio is supported. On mine, those side locking clips put pressure on the faux wood panel and carried all the weight, cracking it at the bottom corner. I used a small screw on the back side of the radio, attached a small angled bracket, and screwed to a wood block sized properly, which had been screwed to the plywood under the dash (cautiously). This carries the weight of the back of the radio to relieve the pressure at the front plate.
