Can’t find year of boat

[Gagec22]

I have a Montgomery ward sea king 12ft aluminum vhull. I bought it off of Facebook and can’t find the year of it. The serial number is G4-5897 and the model number is 60-8923. I’m lost and have looked everywhere. I’m trying to make a jet Jon and cannot register it without the year. Pictures are of the tag on it and the boat itself. Please help me i also can’t seem to find a hin.

little late to this party, but for what it's worth, it appears model 8923 fall into the 1965 model year.
