This are made to work in conjunction with our 10.4 LCD Bezel. It can be used with the factory Countercade as well but the holes will not match. You will need to redrill new ones in the factory Countercade bezel. If you are using our 10.4 bezel you will still need to drill holes as well. Our bezel is very soft wood and you can easily put the screws in without pre drilling but for ease we would suggest to go ahead and pre drill anyways.
