While installing a leading edge slat drive rotary actuator on the left wing Number 5 slat I realized that when I did the same job on another day on this Aircraft X on the right wing Number 6 leading edge slat that there was a spacer that was not installed on that actuator. The missing spacer will be installed before further flight; a write-up has been made.
Technician working on a B757 discovered missing spacer on wing leading edge slat actuator.
