Took a looksie and came across an old(er) True Ames Caserio wave fin that I converted to Powerbox back in the day. It's a 8.5". Sweet fin from what I remember!
What board/sail size are you looking to fin?
Edit: Just looked back and saw you wanted one for what would be, I'm assuming, your larger board and your 6.0...the Caserio would be waaaay too small.
I still have a few US box surf fins in 9" and I think one 9.25" but dont know if you want to mess around with the conversion process. Do they even sell Powerbox adaptors anymore?
