I found a few SPEEDFINS brand fins when I was cleaning the garage. I don’t have a board with this system any longer so I listed them on ebay before thinking I should offer them to some fellow swaylockers who may need them. I have a trailer and right side rail fin. They are both black with 4.5" heights and 4.25" bases. Not sure about the material, has a strange sound when you tap them, ceramic maybe? The template or model is S115. Let me know if anyone is interested, shouldn’t cost much to ship, maybe we could barter…
