I'm sure this has been answered elsewhere on UTGF, but...

So why do the GC guitars have a wider nut than the GA guitars do?

It's not about the body shape, it's about the series.
100-200 series Taylor's have 1 11/16" nut. 300-900 series have 1 3/4" nut

Then Sweetwater is wrong.  They have the 512ce as having a 1 3/4 nut and the 514ce as having 1.6875, which seems to me to be 1 11/16.  I could be wrong on the conversion but it seems that they would have said it 1.75 if it were 1 3/4.

Typo!

It's possible to custom order a 514 with a 1 11/16" nut, but it would be a special order for a customer. Most likely it's just wrong data published. 514s will have standard 1 3/4" nuts, as will a standard 500 series Taylor of any body size.

Cool, thanks.

I don't think they do; the Taylor specification sheet shows both with a 1-3/4" neck width...
