Location of Hull ID in kayak

Hello group, I purchased a used Malibu Stealth 14 from another angler who customized it with a motor mounting bracket at the stern. The aluminum mounting plates cover most of the rear section so I can't see if there is a Hull ID number underneath, which I need to register it under my name. If you own a Stealth 14, do you know where Malibu stamped the Hull ID number? I'm hoping it's not in the stern area. Any ideas?...
