A Hi-Torque, or coin slot bit will also do the job with a socket wrench 
that most folks are more likely to have. I use these mostly with an air 
impact wrench for removing and installing plate screws, but one of these 
with a socket wrench works way better than a brace and bit - which I 
also have used. I use #4 for smaller screws like the pressure bar screws 
at issue here, and #5, with some light grinding modifications, on the 
big screws.

I've been told a drag link socket works too, but I know from long 
experience the hi-torque does.

Marshall,
Lots of ways to go that will work, but the quick way with what you 
already have is a tap with a hammer on the screw head, followed by a 
Crescent wrench (for leverage) on a BIG flat blade screw driver.
