Thanks for flipping the picture. I totally understand and I see how it would work with my formula.
I'm sold.

Update

I just tried the new FCS II fins in a probox.

All you have to do, is take a hacksaw and cut the tab off that extends beyond the front of the fin. Perfect fit.

Plus the tab is much bigger, making it stronger.

You loose some fore and aft adjustment though. But if really needed, you could just cut more of the tab off.

They are selling a lot of fins pairs, in the FCS II system. Good for us.
