Moving handlebar mounted turn signals to headlamp bracket

Hi Folks, I have a 1982 KZ550C LTD. What would it take to move my turn signals from the handlebars to a headlamp bracket configuration? I believe the Z550's were set up like this. I know they had rectangular turn signals while mine are round,  What model KZ;s or other might be suitable to use for parts? Thanks!

simplest way. replace the big headlight bolts w turn signal stems. and reuse the stock turn signals.
