Gen3/4 all you have to do is remove the forward instrument cluster panel, which is one big panel containing the headlight adjusters... I think 4 screws. Battery and glove box panels stay in place.
I only had to remove one. The one surrounding the instrument cluster that goes all the way from the left to the right.I'm a little confused. Since I have a Gen2, I have to remove 4 panels to access the mirror mounts. Are you saying you only had to remove 2?
