Dads50, my drums look just like yours. Mine have the Pac-Man hole too. I just find it funny how the 1960 shop manual says that I am supposed to just turn the adjusting wheel in, and the drums should come off. Never said anything about having to undo the backing plate and axle nut. Maybe I'll have to post pics. I'd love to get this truck on the road very soon, almost tempted to have whoever inspects it check the brakes, but they might not even know what to do with this old relic!
