Hi all,
I bought a 2nd hand board.
There is only a bolt at rear like the photo, there are 4 blocks slidable.
It is about 3.8 cm deep.
Can anyone tell me which fin should I buy please?
Power box?

Thanks a lot!

Sounds like a Tiga/Bic trim box

Trim box fins are above. Not to be confused with US box and different also to Tiga conical box.
