On my first Contour when I was trying to remove those caps to upgrade the speakers, I f'ed up the sail panel. When I upgraded the speakers on my SVT, I knew better and opted to drill out the $2 screw caps rather than mess up the $30 sail panels (not sure what they really cost, but more than the caps for sure). Supposedly duct tape has worked for people, but they were in too tight for me.
