stepping mast

Hi all- Stepped the mast on a Hunter 326 that I just bought. I looked through the manuals and couldn't find any reference to needing any type of pin where the mast meets the step. Does anyone know if this correct? I can see how the standing rigging holds the mast down to the deck and secures it...

Because the mast step is under the seat I cannot attach the mast at a mast step pivot point so it is impossible for me to lift the mast in place at the step. Any suggestions as to how to do this alone other than ‘start lifting weights’ ?
