The Gamakatsu 2234 is the same as the Eagle Claw 630 that the mold is made for. That hook will work and the 6/0 has a .066" diameter and the 32786 has a .067" diameter, very little difference. You will also have to modify the mold to fit the 60 degree hook while the Gamakatsu 2234 should fit. There is also the VMC 7152 Barbarian jig hook, it has a .068" diameter and may possibly fit that mold. Go to
https://www.barlowstackle.com/ and send them an email and ask them if the Gamakatsu 2234 or the VMC 7152 will fit that mold, you can also ask about the Mustad 32786 60 degree hook. They will try them and let you know if the hooks will work. Now the 2234 has a sproat bend which you may not want but it will make the hook that much stronger and when you hook a fish it will be harder for it to throw the hook. The VMC has a deep throat design that does a great job of holding fish as well so if either of those hooks fit they should perform extremely well. Good luck to you and please don't be a stranger stick around here with us.
