If your seat pin is missing, perhaps this 5/16" quick release seat pin for the Shoprider Echo (SL73) lightweight mobility scooter will do the job.
This is the correct replacement 5/16"" x 3-1/8" pin with the ring that helps secure your Shoprider's seat for safe ride. Although this pin was made especially for the Shoprider Echo (SL73) it can be used on a wide variety of mobility applications.
Small and rarely seen, but no doubt absolutely needed to ensure that your seat is always secured proper to the base.
