first and foremost before you do anything unhook the battery !!!!! i learned long ago when messing with wires unhook battery or you could burn your car to the ground i almost did !!!! you were warned !!!!!
next we need to remove all the screws holding down the speaker cover they are t15 torx and i believe they are also 7mm the heads are both sizes. some of them i use my cordless screw driver with a 12"extension 1/4 drive in the drill for quick screw removal. some you will want to use the 1/4 socket with the t15 torx with a ratchet.you will see the big split in my dash which is the reason for this whole thread its been pissing me off for over 5 years so yesterday was the day it got fixed.
next we have all the screws actually holding the top part of the dash pad to the base of the windshield there is 4 and they are also t15 torx and i used the drill with long extension with a socket in it to remove them.
