Sick of googling and not having much success, I'm looking for a larger us box fin to use in my 90ltr carve, something around 28cm.
Will be used with 5.4 and 6.4 NP Excess sails in bump and jump conditions around the 18-25 knot wind range, my weight is 95 kgs.
Can anyone suggest something that may suit ? Would ultimately like to get hold of several s/hand options otherwise one new one.

Black project do a fsw in US box, 28cm.

I've got a 28cm black project FSW used twice gathering dust in my shed - I don't have a us box board - flick us an email if ya keen - it's a great fin

They are hard to get.

If russh's ooption isn't a go-er, try this:

True Ames also do several, (see trueames.com/t/wind/mount/american-a) but it is hard to find online retailers who ship True-Ames to Australia. I found Windance Boardshop good with the True-Ames fins. They even list some models in US base that the True-Ames website doesn't list as available. www.windance.com/True-Ames-Teardrop-32cm-WSWF374732PB/
