I cannot seem to locate that diagram In my Chevy truck manual for the 1948-1953 trucks where it shows those lock screws....under rear axle section page 4-21, it does show the differential and I can clearly see the pinion bearing but not the lock screws...I am trying to visualize" how" those lock screws perform their function of securing the pinion bearing.

1953 chevy 1/2 ton with 3 speed 318 on floor and 1955 235 engine
