VariSet and Guidance Longboard fin adapters

I’ve designed and bench tested adapters for vintage VariSet and Guidance fin boxes that allow you to install a modern longboard fin. Looking for feedback and interested parties to water test.

I’ll be sending prototypes to a vintage board enthusiast in HI that loaned me a number of boxes so these could be designed. I currently sell Futures and FCS II to longboard adapters on eBay but looking for feedback and some water testing before I consider selling these.

If you have a 3D printer and would like to print and test reach out and I can share the STL files and answer any questions. Only thing needed are some longer screws but you do need the original VariSet Plates for that model.

Take care

Hope you’re not thinking you might get rich on this.
