I'm confused by what you mean by "hook on mast step". Is something already attached to the holes in either the mast bottom, or the base that receives the mast?
The original Hobie 16 mast base had a hook that engaged a pin in the mast base to help raise the mast. Only problem was that the hook had a bad tendency to disengage when the mast was about half-raised.
Hobie Cat quickly introduced the mast step link kit. Older boats could be easily retrofitted with it.
