Re: windshield latch
Freon, I don't think he was questioning the year... I think he's saying it's doubtful you'll find a matching one that old.
There's a guy in Reynoldsburg or Pickerington OH, who advertises on craigslist in Columbus, who scraps out old boats. You might look for one of his ads, and respond to it with your question. I've bought things from him before, and he's pretty reasonable.
Good luck.
