How is a ‘61-2 gibson J45 different from a ‘63?

[TheLeadFlatpick 16]

Hi, so I’ve been looking at 60’s J45 and I was looking at an article about the history of the J45 (article here: http://truevintageguitar.com/the-gibson-j-45-model-through-the-years/) and I noticed the era 47-62 and 62-68, and I was wondering what the differences are between a ‘61 J45 and a ‘63 would be? Im looking at trading for  a ‘61 cherry burst tomorrow and I couldn’t find any articles explaining the differences. The ‘61s seem to be worth more than the ‘63s, but I didnt find any differences, was a ‘61 lighter braced or was the body wood beefed up in ‘63? Any help would be appreciated, as well as cautions

Edit: I dated the guitar that Im looking at by the FON on the back of the headstock, its also a cherry sunburst finish, stamped J-45 ADJ BRIDGE

1961 J-45 would have a Q-prefix FON ink-stamped on the neck block. 

This website has some good info. The link below may not work, but you should be able to take the info and find the site
