I recently got a new head unit for my WRX sedan. I was looking around the dash to find a way to take it apart but I didn't find any screws. Can anyone tell me where the fasteners that hold the dash in place are? Also, are there any special tools that I'll need to momentarily steal from my husband, to take it apart? Any help in this matter will be greatly appreciated since I really don't want to have to keep the stock stereo in there much longer.
