Hull number location for 1976 Seacraft cuddy

[clifc]

Hi can anyone out there help me in locating a second hull ID number. My boat hull has been refinished and there is no sign of original hull number. I am in the process of trying to register the boat in my home state prior to taking it down to Baja and was told by the former owner that there may be second hidden hull number location. Any help would be very much appreciated. Thanks
