Ocean Kayak Torque Prop Replacement Pin

We have 4 ocean kayak malibu pedal kayaks which require the pins for the pedal drives to function. Salt water and running into objects or frequent running aground can break the pins to prevent damage to the pedal drive. Having extra pins in the pedal drive compartment provides security that pdl issues most likely could be resolved instantly. TGwatersports is the only carrier of the pins that I could find online, besides through reputable ocean kayak/old town authorized dealers. Price and shipping is reasonable and fast and exactly what we need for that security on the water.
