The Stovebolt Site Forums The Shop Area General Truck Talk Clutchhead/Phillips head

I am taking apart my latest find a 1941 GMC COE. I was surprised to find only Phillips head screws, not just a few, all of them, from the trim all the way to the large door hinge fasteners and even the big ones that hold the lower cab together. At first I thought maybe they were replaced during a rebuild but I am almost finished with disassemble and have yet to find a clutch head screw. Even the little guys under the ash tray. My 41 GMC pickup has them need to check my 45 panel. What gives? Dave
