Feel free to add sources and names of parts that you think would be useful, but here’s my discovery. The little plastic thingy that keeps the Zoom seat back at the proper elevation in my Perception Carolina Kayak broke. By calling Perception I discovered that it has a name - Butterfly clip - and that it’s separately available rather than having to buy a whole new seat back. Perception doesn’t sell them and they referred me to TopKayaker.com where they’re listed here:
Similarly the plastic clips that holds the foot pegs in place broke making my rudder control useless. The foot pegs are replaceable - Keepers Foot Pegs. When I took one out of my kayak today I noted that the springy clip part that broke was a separate piece. I learned from TopKayaker that the clip is called the “trigger”, but unfortunately triggers are not separately available and you have to buy a whole new peg when that breaks. Apparently they’ve been trying for years to get the company to sell the triggers separately or find someone who manufactures them. One of you 3D printer gurus could make some $ if you designed and printed these - assuming you could print them in a relatively flexible plastic that wouldn’t fatigue and break.
