I am having problems with a hook for this mold in the smaller heads.It calls for a gammy 604 but they are too expensive. Do you know a different hook I can use that will fit the smaller heads on this mold?

Not sure which mold you have, but hopefully this will help.

Barlows shows all the hooks that are universal.
