I have a 1995 F150 and want to change the factory am/fm cassette that came with it. There seem to be 4 screws recessed in at the corners. Anyone know what head they might be.
Thanks

 

they aren't so much screws, but holes to press a spring loaded "lock", which secures the deck. You can buy the "keys" for like 3 bucks at car parts stores and wallymart. Ford radio removal keys/tools. insert pull apart and pull towards you all with one motion ... easy...!
