The screw which holds the Retainer to the motor is #10-24 X 3/8 with a #10 washer
The screw which holds the Retainer to the header bar is #10-24 X 1 like the AMK picture.
And yes the production washer does appear to be larger, now these are from an original 64 car however don't believe
anything changed for 64-67, per parts listing.
PS unable to measure those, they're on the car.
