The boy does not match a 62 like noted above, but who knows. I have a 61 sold in 62, it now has a cigarette lighter in the same place as later years, once I was told it was not factory I can now see the hole was well cut, but the notch part was not as well cut as the others. I have the original bolt latches, but came with the parts like yours, I will likely switch my windshield latches. I like to have the windshield down a lot, so the quick handle is a lot more appealing then getting a wrench out. Point is people could have put a new body on it in the last 50 years, as well as modified it. Even the pillars could have been nicely modified to fit a later hard top at one point.
Super nice rig no matter what, can't wait to see a lot more pics.
