1979 kz 650 sr handlebars

Hi all. I just returned from my very first ride on my 1979 kz650sr. I love my bike! I really only had one issue with the bike. The handlebars are not original. The rise is lower by an estimated 2 inches or so. I would love to replace them with the bar type that came with the bike. Is there anyone here that can tell me where to find such handlebars or at least give me the dimensions of the original?
