The large blinds in our 3670RL pulled out of the wall on one side. It's held in by a screw that goes into the wall. I'm able to pop it back in, but does anyone know how to remove thE valence so you can get at the screw if you want to put a bigger one in? Only way of getting at it w/o removing the valence and side panel would be with a short right angle screw driver?
