The vents don't come out fella. I vaguely remember a post awhile back on ClubXX where someone was doing the exact same thing and they tried to take them out and broke them. Some people claim that you can remove them will a small flathead screwdriver but i wouldn't reccomend it. You know how flimsy ABS plastic can be....so i would just reccomend covering the vents with painter's tape. After the dash trim piece is off just move the vents up and down, manipulate them however you need to, and try to "thread" the tape from the back of the dash trim piece(in the area surrounding the vents) over the top of the vent, over the front of it, and again over the bottom part of the vent...hope that makes sense. Good luck!
