From the pics, description, and emails with the seller, it appears this is a special order '65 GT convertible, A-code 4-speed, limited slip 3.00:1 rear, original paint. Although it's hard to tell from limited ebay photos, it appears to be Pace Car White (or Pure White, as it appeared in the Ford truck paint options):

Of course, without an original window sticker or the build sheet, the special order color may never be known.
