WTB a not needed Aquacraft Rio 51 turn fin

[Ronbo]

If anyone has an uneeded/or unused Aquacraft Rio 51 left turn fin, I would like to buy it take it off their hands. Preferably less than i can buy the package. They are currently 25-30$, Id like to buy it much less than the 15$ if possible for the one. The other fin is useless for my application.

I realize i can make one, just not right now...

PM or respond if you can help. Thanks...
