The Victory 10604 will fit in the following sizes...
1/32 cavity - will not fit
1/16oz. cavity - 1/0 & 2/0
1/8oz. cavity - 1/0 & 2/0
1/4oz. cavity - 3/0

The reason the hooks don't fit is the 604 the mold calls for has a shorter leg than the other hooks. Try a VMC 7249 or the Victory 10604, both of those should work.
