M_Boats: CB stopper pin

Hi folks, Tomorrow is "replace my frayed CB pendent "day. I will lift the stern of my M-17 from some beams in my friends barn. I looked today for any indication for the 3/8" stopper pin where the CB's hook comes to rest. Is there a measurement from the pivot bolt ? I will keep searching tomorrow. Also it needs to be driven out from port to Starboard ? or visa versa ? Thanks, Doug Vogel Tie Line #325
