Can't find them anywhere without buying a full set at $300

not an option for
just trying my 5 boxed board (supplied as a thruster) as a quad.
I'd like to find the main fins from an MFC quad set - the 350cm2 or 400cm2 - the mains should be 15.5cm long. The nice upright (not raked) G10 ones. Or the newer red / white ones that I think are still G10 and just painted
I loaded a pic and seabreeze is having a brain fart and won't them let me put it in here......
Stuffed up ones u ran over the reef is just fine (if not preferred

)
Anyway, $$$$$ or swap as I have tons of smaller ones.
