A year and a half ago, I put a new radio into my 2012 Ford E-350. This week, I needed to take it out in order to fix some other things.
When I tried to use my ratchet to remove the screws, three of the four screw heads snapped off. I have tried to use a pair of pliers to turn the remaining portion of one of the screws, but all I manage to do is further snap it. I'm really not keen to do that to the other two as well. (These are the original OEM radio screws.)
How can I remove the remaining pieces to be able to replace them with new screws?
