how do you get the vents out of the dash board? i just cant seem to get out the vent bezel to get to the bolts behind it for the dash board. im afraid to break them but they have to come out. i dont know if there is a special tool to decompress the clips some how or what....these have to come out one way or another weather it be in pieces or as a whole...i would prefer it to come out as a whole though. lol.
